Are you trying to decide whether or not to neuter your dog? Like any other medical procedure, there are pros and cons to neutering and dog owners should consider them carefully before deciding on next steps. Here are some of the potential risks that comes with not neutering your dog.

Increased Risk of Prostate Diseases or Infections

Dogs that aren’t neutered have a higher chance of getting affected by prostate diseases or infections. Benign prostatic hypertrophy is one example and can be seen more frequently among un-neutered dogs after the age of 5. Other common prostate diseases include prostatitis and prostate cancer.

Maintains Aggressive Behavior

There are behavioral benefits to neutering your dog. Neutered dogs, for example, are less likely to exhibit problematic behaviors than dogs that have not been neutered. Having this procedure done is not a fix-all solution to a dog’s problematic behavior (e.g. aggression, mounting, and territory marking inside the house) but it could help keep those instances to a minimum.

Increased Risk of Dog Escaping

Male dogs that haven’t been neutered may have a strong urge to escape when they sense there is a female dog in the vicinity that’s in heat. Neutered dogs may also react to the presence of a female dog in heat but not to the same extent (as they no longer produce testosterone). Dogs can get quite creative with their escape plans so it’s something that dog owners will need to pay extra attention to especially if there is a big dog community in their area.

Increased Risk of Unwanted Breeding

Dog owners who decide to not neuter their pet will need to monitor their dog more closely and make sure they aren’t having close encounters with female dogs in heat. This is one of the biggest reasons why animal shelters campaign hard to get pets neutered or spayed. Unwanted breeding is a big reason why animal shelters are getting overcrowded and pet owners need to play their part in making sure dogs aren’t getting pregnant unless intended.
