What Is The Best Age To Neuter A Staffy

Updated April 13, 2021

Whether you call it neuterspaycastrate or desex, the right time to get it done in dogs is a subject of much debate. This is because it varies from breed to breed. Recently, a study was published on the best age for neutering 20-29kg dog breeds like the American Staffy (AmStaff) and Staffy crosses.

English Staffordshire Terriers would probably be most similar to Kelpie desexing times.

This paper provides the first evidence for larger dog breeds on choosing a time of desexing with the fewest health problems. The study compared the dogs neutered at different ages for their rates of:

All of these have been suspected to be linked with the age of neutering. Here’s what they found (only bold values are significant, my summary to follow):

Joint Disorders. For ages 1 through 11 years and for each neuter period. Bold values indicate significance over the intact group. The asterisk (*) indicates when there was significance using the Wilcoxon test, but no significance using the log-rank test. The dagger () indicates significance when the early groups (< 6 mo. and 6-11 mo.) are combined.

UI was diagnosed in 3 percent of females spayed at less than 11 months.

Summary: The Best Staffy Spay & Neuter Times

Joint problems were more common in 20-29kg dogs desexed under 1 year of age. UI was also more common in females.

Recommendation: 1 year for both sexes, but the decision may be based on other factors such as:

The study authors are to be applauded to bringing into focus one of the most common questions from dog owners. For the Staffy at least, they’ve made the decision a lot easier.
