You are going to get a lot of different answers to this question. Some people say you should do it daily, some say weekly, and some say it’s okay if you get the vet to do it, every couple of months. We think this is something that should be left to a vet, although between sessions you can do the best to keep your pet’s teeth clean. There are pet toothbrushes, there is special toothpaste, and some pets quite enjoy the process.
If you can brush your pet’s teeth on your own, and your pet will allow you to, then do it. But it’s still a good idea to visit the vet on an annual basis for a little dental hygiene!
