The problem with using homemade treatments is that your dog will swallow it – so you want to avoid the type of things that humans would use in place of toothpaste such as baking soda.

The commercial canine toothpaste has enzymes that help delay the growth of plaque, and this is something you can’t replicate in a home made products.  Canine toothpaste is not very expense, and a tube of it lasts a long time, well worth the modest cost.

Dr. Dawn is correct – you must get the second dog neutered, and even then you need to keep these dogs apart (so they can’t even see each other!) for several weeks afterward.  This gives time for the testosterone to work its way out of the new neutered dog’s system.

Then, get the help of a professional behaviorist to reintroduce these two dogs – don’t attempt it yourself because they now have a history of aggression and will associate this aggression with each other.  You need someone that can read the tiny signs a dog gives when they are uncomfortable with another dog.  Even your own fear of something bad happening can trigger aggression between these two, so find a way to get help.  If nothing else, contact your local SPCA and tell them your situation – and ask if they have someone that can help you, maybe a volunteer or a trainer that will help at a reduced cost.  Explain that you are trying to avoid having to re-home one of the dogs and maybe they can help in some way.

Good luck – and don’t wait to get that boy neutered!
