How often do you brush your dog's teeth?

How often do you brush your dog's teeth?

I dont,i use those dentastix things,and she also has dry kibble sometimes,to help keep teeth clean.

Kaiser doesnt need it i just have loads of chewy bones and he is on kibble so his teeth are lovely and white although he does get spoilt with fresh meat i.e liver, chicken and even lately he has been getting grilled steak eats better than me lol

I think if i tried to brush his teeth he would just eat the brush. But his teeth are pure white and his breath is fine.
Been trying to find out what food he likes so to the smells at the other end are more of a concern at the moment

i use those dentastix aswell i give her a shin bone every week aswell seems to do the trick
