My baby girl is almost 16 weeks old (this Sunday) and I am wondering when should you brush a gsd puppy's teeth? I am not wanting to go to a vet or groomers' to do this. I want to do this at home. When Should I start? I also saw these things called "greenies" that they can chew on to clean their teeth? Is that sufficient enough to keep their teeth clean? Also has anyone ever made Home made tooth paste for their gsd? I know I have alot of questions, I figure it's better to ask them all at one then writing several new topics on the forum.
