Spay and neuter in rescues
The common practice of sterilising dogs before or soon after adoption, set by shelter or rescue policy to prevent unplanned litters.
Also called: spay neuter contract, pre-adoption sterilisation, pediatric spay neuter, spay/neuter requirement, altered before adoption, spay neuter agreement
Most shelters and rescue groups require dogs to be spayed or neutered before they go home. If a dog is too young or not ready, the adopter usually signs a contract promising to have it done by a set date, and some groups hold the dog's papers or a deposit until proof arrives. The goal is to prevent unplanned litters, which add to the number of dogs entering shelters.
Many groups sterilise puppies at a young age, often at about two months old if they are healthy and weigh enough, while others wait until the dog is older. The timing of the surgery for your own dog is a medical question to discuss with a veterinarian, and it can differ for large breeds.
The cost is often part of the adoption fee. Some breeders also require sterilisation in a contract. Ask a dog rescue or animal shelter what its policy is, which clinic does the surgery and what follow-up care is included.
