Why I Donāt Recommend Early Spay & Neuter
Iām absolutely not anti-spay/neuter. I believe responsible pet owners should make a thoughtful plan to prevent unwanted litters and, when appropriate, eventually spay or neuter their dogs.
What I don't recommend is automatically spaying or neutering every puppy at 3, 4, or 5 months simply because that has traditionally been the standard advice.
We know more now.
Research from the UC Davis School of Veterinary Medicine has shown that spay/neuter timing can matter, and that the effects can vary considerably depending on the dog's breed, s*x, size, and age at the time of surgery. In some breeds, early alteration has been associated with increased rates of orthopedic problems such as hip dysplasia, elbow dysplasia, and cruciate ligament injuries.
Why might timing matter? Reproductive hormones such as estrogen and testosterone play important roles in a puppy's normal growth and development, including the development of bones and joints. At 3 or 4 months old, a puppy has a lot of growing left to do.
That's why I prefer to let my puppies mature before they are altered, whenever their individual circumstances allow it.
This doesn't mean that every dog should remain intact forever. There are real considerations to waiting, including accidental pregnancy and health risks such as pyometra in females. Delaying spay/neuter requires responsible ownership and careful management.
My goal is simply to encourage families to have a conversation with their veterinarian about when the procedure is appropriate for their individual dog rather than treating a particular age as a one-size-fits-all rule.
Breed, expected adult size, s*x, lifestyle, family history, orthopedic risk, and the owner's ability to responsibly manage an intact dog all deserve consideration.
When I place a puppy in your arms, I'm thinking about more than the 12-week-old puppy you're taking home. I'm thinking about the dog I hope will be healthy and happy at 2, 5, 10, and hopefully 15+ years old.
I'm pro-responsible spay/neuter. I'm also pro-growth, pro-research, and pro-making thoughtful decisions based on the individual dog.
