There are many medical benefits to neutering a male French Bulldog earlier in life, as it can prevent certain prostate issues and testicular cancer. The behavioral benefits of male French Bulldog neuter include reduced urine marking, decreased mounting of other dogs, people, or objects, and a likelihood to keep from wandering. Male dogs left un-neutered are apt to roam and escape their home to find a mate, putting them at high risk of running into traffic, territorial or aggressive animals, and other natural dangers beyond the safety of their home. Some breeders will have the new owner of a French Bulldog puppy sign a contract that promises to neuter or spay their French Bulldog within six months to a year from the dog's birth. There is a consensus among veterinarians that the best time to neuter a male dog is within six to nine months of birth. It is possible to neuter male dogs later in adult years, but there are certain risks related to age, health, and weight that may occur. A French Bulldog owner must make this decision based on many factors; however, if the decision to neuter is made, it would be best to have the operation done before the first year after birth.
