Can Neutering Lead To Cognitive Impairments In Dogs? The Answer May Surprise You

Neutering is a very common process for many dogs. But, as with all procedures, it comes with its share of pros and cons, including risks.

Not all dog owners decide to neuter their dogs, but if you’re considering it, you should know about a particularly concerning risk: cognitive impairment.

Dementia and other forms of degenerative cognitive disorders become more likely as your dog ages, but neutering can also increase that risk. Research indicates that neutered dogs experience more loss of training retention compared to intact dogs, especially in male dogs. This can also cause behavioral changes due to memory and learning loss.

Alzheimer’s, another degenerative disease, is also affected by neutering. This is because testosterone, the hormone found most in intact male dogs, protects against the disease. Estrogen, the hormone found most in intact female dogs, also helps to keep memory and brain function fresh. Because neutering reduces the amounts of these hormones, these dogs can lose the protective barrier they provide.

A potentially safer alternative is leaving glands intact during neutering. Another option is the use of hormone replacement therapy. However, some people do believe that the benefits of neutering outweigh its rare risks. The final decision is ultimately up to you.
