Yesterday I made the rounds at the California state capital to visit the offices of the Assembly Business & Professions Committee members to discuss AB 1634. I was accompanied by two police officers who discussed the harmful impacts AB 1634 would have on law enforcement. Also with us was the person in charge of the breeding and training program at Canine Companions for Independence (CCI), who discussed how AB 1634 would harm programs that assist blind and disabled Californians. He also represented Assistance Dogs International, Inc., an umbrella organization over many guide/service/hearing dog organizations.
Similar to guide dog programs, CCI breeds and trains dogs to assist disabled people. They use Golden Retrievers, Labrador Retrievers, and Golden/Labrador mixes. CCI breeds over 600 dogs a year.
My jaw nearly hit the floor when the CCI representative started describing research that CCI did in the early 1990s to understand spay/neuter impacts. CCI wanted to know if early s/n (less than 6 months of age) would yield results at least as good as their traditional spay/neuter age, which is usually over 12 months of age (typical is 17 months of age). So CCI did a controlled prospective research study... the gold standard of research to understand cause-and-effect.
CCI assigned half the pups in a number of litters to be s/n early, while the remaining pups in these litters were s/n at their traditional age. The results were very unexpected. The early-age spayed females were significantly more dog aggressive than the traditional-age spayed females. Urinary incontinence was a much bigger problem in the early-age spayed females compared to the traditional-age spayed females. The early-age neutered males were more fearful than the traditional-age neutered males. The bottom line is that the early-age spay/neuter dogs had a significantly higher failure rate in CCI's program... a smaller percentage of them grew up to be working dogs. As a result, CCI will not spay/neuter dogs before 6 months of age, and usually wait until dogs are more than 12 months old to spay/neuter. The CCI rep said this research has been repeated by others. I believe one of them may be Guide Dogs for the Blind, as I was told by one of their trainers that they recently stopped doing early spay/neuter owing to results they were seeing that they don't like.
