What products should I use to brush my dog's teeth?

You want to use pet toothpaste, and preferably one that is certified by the Veterinary Oral Health Council or the VOHD. At the moment, there's only one, and it's called pet smile. It's right there. It has several different flavors: beef, chicken, cheese, and it's nice because it's enzymatic. So it works even if you can't get the actual physical brushing motion on there.

They make specific toothpaste for dogs, and I always recommend using one of those products.

They make toothpaste specifically for dogs. That toothpaste has everything safe for a dog to swallow because as hard as it is to get a dog to brush their teeth, it's really hard to get them to spit. So you don't want to use human toothpaste because they will swallow that, which can upset their stomach.
