Hi Jimmy. I do brush my bullies teeth. If you start brushing their teeth from a young age, they will be used to it and won't mind you doing it. You can buy many different dog teeth cleaning products at Petsmart or any other pet supply store. I bought the Arm and Hammer brand of toothbrush for dogs, it came in a package that contains a regular toothbrush, and a finger toothbrush, and beef flavoured dog safe toothpaste, never use toothpaste for people as it dangerous and toxic for animals. I usually brush their teeth once every two weeks, usually before their bath. I sit on the floor, and have them sit between my legs with their body facing away from me. I place their head on my chest, and then brush their teeth, they like the taste of the toothpaste as it tastes like beef, and then just let them drink some water to clean it off. My groomer is also certified in scaling and cleaning teeth for dogs, and so about every two months, I take them to her to have their teeth scaled and brushed by her. I like taking them there instead of having my vet do the cleanings of their teeth, because she would put them under anesthetic, and there's too much risk of complications to do this for teeth cleaning. If you maintain their teeth from a young age, and give them bones to chew on, you can keep their teeth clean and avoid dental problems. There is also a product called Fresh Clean, it is a green liquid that you put in the drinking water, it removes plaque from the teeth, kills bacteria, and has a minty taste to freshen the breath.
