Adoption: The process of transferring ownership of an animal from a shelter or rescue to a new permanent owner. Modern shelters use digital adoption applications with e-signatures to streamline the process and reduce paperwork.
Adoption Application Operations: A form completed by prospective adopters providing information about their household, experience with animals, and living situation. Digital applications can be shared remotely, allowing adopters to apply before visiting the shelter, speeding up the process.
Adoption Contract Legal: A legally binding agreement between the shelter and adopter outlining responsibilities, spay/neuter requirements, return policies, and care expectations. E-signature capability allows contracts to be signed digitally on the spot.
Adoption Fee: The charge an adopter pays to the shelter when adopting an animal. Fees typically cover spay/neuter surgery, vaccinations, microchipping, and deworming already provided. Fees vary by species, age, and organization — commonly $50-$300 for dogs and $25-$150 for cats.
AKC Reunite Platform: The American Kennel Club's microchip registration and pet recovery service. Pet Friend integrates with AKC Reunite to streamline microchip registration for animals at intake or adoption.
Animal Control Operations: A government agency or department responsible for enforcing animal-related laws and ordinances. Officers respond to calls about stray animals, animal bites, cruelty complaints, and licensing violations. Also known as dog wardens or humane officers in some jurisdictions.
Animal Cruelty Legal: The intentional or negligent mistreatment of animals, including abuse, neglect, abandonment, and hoarding. Animal control officers investigate cruelty cases and may seize animals as evidence. Cases are tracked through shelter software with detailed records for legal proceedings.
Behavior Assessment Operations: A standardized evaluation of an animal's temperament, sociability, and behavioral traits conducted after intake. Results help determine placement suitability, identify training needs, and provide adopters with accurate behavioral information. Common assessments include the SAFER test for dogs.
Bite Case Legal: An incident where an animal bites a person or another animal. Bite cases trigger mandatory quarantine periods (typically 10 days for rabies observation), require official reporting, and are tracked with detailed records including location, severity, and quarantine dates. Animal control officers manage bite investigations.
Bordetella Medical: A highly contagious bacterial infection (Bordetella bronchiseptica) that causes kennel cough in dogs. Vaccination is typically required for dogs entering shelters, boarding facilities, or group housing. Symptoms include a persistent dry cough, retching, and nasal discharge.
Census Operations: A count of all animals currently housed at a shelter, typically broken down by species, location, and status. Census reports help shelters monitor capacity, plan staffing, and identify trends in intake and outcomes. Shelter software generates census reports automatically from current records.
CLIA Waiver Medical: A Clinical Laboratory Improvement Amendments waiver that allows shelters to perform simple diagnostic tests (like FIV/FeLV snap tests or heartworm tests) on-site without a full laboratory license. Many shelters operate under CLIA waivers to speed up medical screenings at intake.
Community Cat: An unowned free-roaming cat that lives outdoors in a community. Community cats may be feral (unsocialized to humans) or semi-feral. They are typically managed through TNR (Trap-Neuter-Return) programs rather than being brought into shelter facilities.
Cremation Record Operations: Documentation of an animal's cremation after death or euthanasia, including date, method (individual or communal), and disposition of remains. Shelter software tracks cremation records as part of the animal's complete history.
DHPP / DA2PP Medical: A combination vaccine for dogs that protects against Distemper, Adenovirus (Hepatitis), Parainfluenza, and Parvovirus. Also called the "distemper combo" or "5-in-1." It is a core vaccine given to all dogs at intake and typically boosted every 2-4 weeks until the series is complete.
Disposition Operations: The final outcome for an animal leaving the shelter. Common dispositions include: adopted, returned to owner (RTO), transferred, euthanized, died in care, and trap-neuter-return (TNR). Disposition tracking is essential for reporting live release rates and other performance metrics.
Donor Management Operations: The process of tracking individuals and organizations that contribute financially to a shelter. Includes recording donation amounts, dates, donor contact information, and generating tax receipts. Shelter software with people management features centralizes donor records alongside volunteer and adopter information.
Ear Tipping: The surgical removal of approximately 1cm from the tip of a feral cat's left ear while under anesthesia for spay/neuter surgery. Ear tipping is the universal visual indicator that a community cat has been sterilized through a TNR program, preventing recapture and unnecessary surgery.
E-Signature Software: A digital signature used to sign adoption contracts, surrender forms, volunteer agreements, and other shelter documents electronically. E-signatures eliminate paper forms, reduce processing time, and create a secure digital record of signed documents.
Euthanasia Medical: The humane ending of an animal's life, typically by intravenous injection of sodium pentobarbital. Shelters may euthanize animals due to untreatable medical conditions, severe behavioral issues, or (in open-admission shelters) capacity constraints. Euthanasia records are tracked with detailed documentation including reason, method, and authorizing staff.
FeLV (Feline Leukemia Virus) Medical: A retrovirus that affects cats, weakening the immune system and potentially causing cancer. Cats are tested for FeLV at intake using a snap test (blood draw). FeLV-positive cats require separate housing from negative cats. There is a vaccine available for FeLV-negative cats.
FIV (Feline Immunodeficiency Virus) Medical: A virus affecting cats that weakens the immune system over time, similar to HIV in humans. FIV-positive cats can live long, healthy lives and are adoptable. Transmission primarily occurs through deep bite wounds. FIV is tested alongside FeLV using a combo snap test at intake.
Foster Care: A temporary arrangement where an animal is placed in a private home rather than remaining in the shelter facility. Used for animals needing socialization, medical recovery, nursing mothers, neonatal kittens, or when the shelter is at capacity. Foster-based rescues operate entirely through foster homes.
FVRCP Medical: A core combination vaccine for cats protecting against Feline Viral Rhinotracheitis (herpesvirus), Calicivirus, and Panleukopenia (feline distemper). Given to all cats at intake and boosted every 3-4 weeks. This is the feline equivalent of the DHPP vaccine for dogs.
Heartworm Medical: A parasitic worm (Dirofilaria immitis) transmitted by mosquitoes that lives in the heart and lungs of infected dogs (and less commonly cats). Dogs are tested for heartworm at intake via a blood test. Treatment for heartworm-positive dogs is expensive and lengthy (2-3 months), but most dogs recover fully. Monthly preventive medication is standard for all shelter dogs.
Holding Period Legal: See Stray Hold.
Home Visit Operations: A visit to a prospective adopter's or foster's home to verify suitability for the animal. Some shelters require home visits before finalizing adoptions, while others have moved to virtual home checks or self-certification forms to speed up the process.
Humane Society: A non-profit organization dedicated to animal welfare. Humane societies may operate animal shelters, run spay/neuter clinics, conduct cruelty investigations, and provide community education. Note: local humane societies are independent organizations — they are not branches of the Humane Society of the United States (HSUS).
Intake Operations: The process of admitting an animal into a shelter's care. Intake involves recording the animal's species, breed, weight, age, condition, microchip scan, source (stray, owner surrender, transfer, seizure), and initial medical screening. Shelter software automates intake with standardized forms, photo capture, and automatic record creation.
Intake Type: The category describing how an animal entered the shelter. Common types: Stray (found at large), Owner Surrender (voluntarily given up), Transfer In (from another organization), Seizure/Confiscation (removed due to cruelty or neglect), Return (previously adopted animal brought back), and Born in Care (born at the shelter or in foster).
Isolation / ISO Medical: A separate housing area within the shelter for animals with contagious diseases (parvo, panleukopenia, ringworm, upper respiratory infections). Isolation protocols include separate cleaning supplies, protective equipment, and restricted staff access to prevent disease transmission to the general population.
Kennel Card Operations: An information card displayed on or near an animal's kennel or cage showing key details: name, breed, age, intake date, medical status, feeding instructions, and temperament notes. Shelter software generates kennel cards automatically from the animal's digital record and can print them on demand.
Kennel Cough Medical: An upper respiratory infection in dogs characterized by a persistent dry, hacking cough. Caused by various pathogens including Bordetella, parainfluenza, and adenovirus. Highly contagious in shelter environments where dogs are housed in close proximity. Typically self-limiting but may require antibiotics in severe cases.
Kennel Management Software: The system for tracking which animals are housed in which kennels or enclosures, monitoring capacity, and managing cleaning and feeding schedules. Shelter software provides visual kennel maps showing occupancy, available spaces, and isolation areas.
Length of Stay (LOS) Operations: The number of days an animal spends in the shelter from intake to outcome. LOS is a key performance metric — shorter stays generally indicate better operational efficiency and animal welfare. Industry benchmarks vary by species: dogs average 14-30 days, cats 21-45 days. Shelter software calculates LOS automatically in reports.
Live Release Rate (LRR) Operations: The percentage of animals that leave the shelter alive through adoption, transfer, or return to owner. Calculated as: (Total Live Outcomes ÷ Total Outcomes) × 100. A shelter with a 90%+ live release rate is generally considered "no-kill." This is one of the most important metrics for measuring shelter performance and is a standard field in shelter reporting.
Lost Animal Report Operations: A record filed when a community member reports a missing pet, or when a found animal is brought to the shelter without an owner. Shelter software allows staff to match lost reports against incoming strays by breed, color, location found, and microchip data to facilitate reunification.
Microchip Medical: A tiny radio-frequency identification (RFID) transponder (about the size of a grain of rice) injected under the skin between an animal's shoulder blades. Each chip has a unique ID number that can be read with a scanner. Microchipping is the most reliable form of permanent identification and is standard at intake and adoption. Chips must be registered to an owner to be effective.
Mutual Aid / Transfer Partner: An agreement between shelters or rescues to accept animals from each other, typically to balance capacity or provide specialized care. Transfer partnerships move animals from high-intake shelters to organizations with open space and higher adoption demand. Shelter software can track transfer records between partner organizations.
Neuter Medical: The surgical sterilization of a male animal by removing the testicles (orchiectomy). Along with spaying, neutering is standard practice for all animals adopted from shelters. Benefits include population control, reduced roaming behavior, and decreased risk of certain cancers. See also: Spay.
No-Kill Shelter: A shelter that does not euthanize animals for space or time, and saves at least 90% of the animals in its care (a 90% or higher live release rate). The term was defined by the No Kill Advocacy Center. "No-kill" does not mean euthanasia never occurs — animals with untreatable suffering or dangerous aggression may still be humanely euthanized.
Open Admission: A shelter that accepts all animals regardless of health, behavior, age, or space. Most municipal (government-funded) shelters are open admission by law — they cannot turn animals away. This differs from limited admission shelters (typically private rescues) that can be selective about which animals they accept.
Outcome Operations: Any event that results in an animal leaving the shelter. Outcomes include adoption, return to owner, transfer to another organization, euthanasia, died in care, and TNR release. Outcome tracking and reporting is central to measuring shelter performance.
Owner Surrender: When a pet owner voluntarily gives up their animal to a shelter or rescue organization. Common reasons include moving, financial hardship, behavioral issues, allergies, or new baby. Owner surrenders typically have shorter holds than strays since ownership is clearly established.
Panleukopenia (Feline Distemper) Medical: A highly contagious and often fatal viral disease in cats caused by feline parvovirus. Symptoms include vomiting, diarrhea, lethargy, and severe dehydration. Extremely dangerous in shelter environments — infected cats must be immediately isolated. Prevention is through the FVRCP vaccine. The virus can survive in the environment for up to a year.
Parvo (Canine Parvovirus) Medical: A highly contagious viral disease in dogs that attacks the gastrointestinal tract, causing severe vomiting, bloody diarrhea, and dehydration. Mortality rates without treatment are 90%+. Most dangerous in puppies under 6 months. The virus is extremely resilient in the environment. Prevention is through the DHPP vaccine series. Infected dogs require immediate isolation and intensive supportive care.
Petfinder Platform: The largest online pet adoption platform in North America, operated by Purina. Shelters list adoptable animals on Petfinder to reach potential adopters beyond their local area. Pet Friend automatically syncs adoptable animals to Petfinder, keeping listings current without manual data entry.
Quarantine Medical: A period of isolation for an animal to prevent the spread of disease or to monitor for symptoms. Quarantine is mandatory for bite cases (typically 10 days for rabies observation) and recommended for newly arrived animals showing signs of illness. Quarantine periods and locations are tracked in the animal's medical record.
Rabies Medical: A fatal viral disease that affects the nervous system of all mammals, including humans. Rabies vaccination is required by law in all 50 US states for dogs and in most states for cats. Shelters vaccinate animals for rabies at intake or adoption. Animals involved in bite cases are quarantined to observe for rabies symptoms.
Reclaim / Return to Owner (RTO) Operations: When a lost animal in the shelter is reunited with its owner. RTO rate is a key shelter metric — a high RTO rate indicates effective stray intake procedures, microchip scanning, and owner notification. Microchipped animals have significantly higher reclaim rates than non-chipped animals.
Rescue Pull: When a rescue organization takes an animal from a shelter (typically an open-admission shelter) to place in foster care or their own adoption program. Rescue pulls are a critical pathway for saving animals in shelters with limited space, especially for animals that need more time or specialized care to become adoptable.
Ringworm Medical: A fungal infection (not actually a worm) that causes circular patches of hair loss and scaly skin in animals. Highly contagious between animals and can spread to humans (zoonotic). Common in shelter cats, especially kittens. Requires isolation, antifungal treatment (typically 4-8 weeks), and thorough environmental decontamination. Shelter software tracks ringworm cases and treatment protocols.
Spay Medical: The surgical sterilization of a female animal by removing the ovaries and uterus (ovariohysterectomy). Spaying is standard practice for all animals adopted from shelters. Benefits include preventing unwanted litters, reducing risk of mammary cancer and uterine infections, and eliminating heat cycles. See also: Neuter.
Stray Hold Legal: A mandatory waiting period (typically 3-7 days depending on jurisdiction) during which a found animal must be held at the shelter before it can be made available for adoption or transfer. The hold gives the original owner time to reclaim their pet. Stray holds are required by law in most states. Animals with microchips or tags may have different hold requirements.
Surrender Form Legal: A document signed by an animal owner voluntarily relinquishing ownership of their pet to a shelter or rescue. The form typically includes the animal's medical history, behavioral notes, reason for surrender, and a waiver of future claims to the animal. E-signature capability streamlines this process.
Titer Test Medical: A blood test that measures the level of antibodies an animal has against a specific disease. Used to determine if an animal has adequate immunity from previous vaccination or natural exposure. Some shelters use titer tests instead of revaccinating animals with unknown vaccine history.
Transfer Operations: Moving an animal from one shelter or rescue to another, typically to increase adoption chances, balance capacity, or access specialized medical care. Transfer partnerships between shelters are essential for the no-kill movement. Pet Friend supports tracking transfer records between partner organizations that both use the software.
Trap-Neuter-Return (TNR): A humane management strategy for feral and community cat populations. Cats are humanely trapped, spayed or neutered, ear-tipped for identification, vaccinated for rabies, and returned to their colony location. TNR stabilizes colony size over time and is recognized as the most effective and humane method for managing community cats by the ASPCA, HSUS, and most animal welfare organizations.
Vaccination Protocol Medical: The standardized schedule for administering vaccines to shelter animals. Dogs typically receive DHPP and rabies; cats receive FVRCP and rabies. Vaccines are usually given at intake and boosted every 2-4 weeks. Shelter software tracks vaccination dates, types, and next-due dates with automated reminders.
Vet Visit Medical: An appointment with a veterinarian for examination, treatment, or surgery. Shelter software tracks vet visits as part of an animal's medical record, including the vet office, reason for visit, diagnosis, treatment, and follow-up instructions. Vet visits can be scheduled through the shelter calendar.
Volunteer Management Operations: The system for recruiting, scheduling, and tracking volunteer workers at a shelter. Includes volunteer applications, background checks, shift scheduling, hour tracking, and generating reports for grants and board meetings. Shelter software with people management features centralizes volunteer records and automates time tracking.
Waiver Legal: A legal document in which a person acknowledges risks and releases the shelter from liability. Common waivers include volunteer liability waivers, foster care agreements, and "as-is" medical disclosure forms for animals with known health conditions being adopted.
Workflow Software: A defined sequence of tasks that must be completed for a process, such as animal intake, daily kennel cleaning, or adoption processing. Shelter software with workflow management lets organizations create repeatable task sequences, assign them to staff, and track completion to ensure nothing is missed.
