My dog humps and gets aggressive. How to introduce him to another dog?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 5 years old | 20 lbs

Hi, I am going on vacation soon to visit my mom and would like to take my dog. He is neutered. However she has a female dog, which is spayed. I am not worried she would get pregnant, but my worry is behavior, social, will they get along etc . Her dog spends most of her time in a backyard, while mine in an apt. My biggest fear is he'd start humping her and become agressive if anyone gets near her. (he did that with another dog he had babies with. Any advice please??? Thank you.

There is no way to know in advance how two dogs will get along. Our best guess is based on previous behavior in similar situations, so if Tigger has had issues with mounting and becoming aggressive in the past, it's very possible it will occur with your mom's dog. I would recommend that if you're bringing him, introduce the dogs in a neutral space (not your mom's house, because it is your mom's dog's space) and have a backup plan to keep the dogs separated or board your dog in the area if the introduction does not go well. Good luck!
