My 5 female dogs fight. What to do about multi-dog aggression?

Updated On September 23rd, 2025

What training method do you consider most effective when it comes to a multi-dog household made up of 5 females (all spayed) that fight when they are all together. The owner does not favor one over the other and toys are not involved, they have an entire acre for the dogs to run, yet it always ends up in a fight.

I'm sorry that you're having this problem! Aggression between dogs in the same household is a complex behavior issue that is a bit beyond the scope of what we can effectively help with in this format. Treatment for this problem involves identifying what triggers the aggression (which often takes a bit of detective work, and observation by an expert) and then finding ways to avoid these triggers, or working with the dogs over time to teach them to respond differently when these situations occur. It's not a simple process, unfortunately, so there's really no quick and easy answer to give. Your best option would be to make an appointment with a veterinary behaviorist who can evaluate the dogs in person and give you some hands-on guidance in dealing with this problem.
