I use these on my dog, and I love it a lot more than the dual ended ones. Since my dog is big, I never had to use the small end on the dual ended one, and it was pretty uncomfortable to hold the small end when brushing my dog's teeth. I got this one because I thought since the brush end is bigger, and it is chubby to fit in my hand, it would work great. It does work great and I love using it. My hand doesn't feel cramped when I use it and it is easy to wash out and store. I totally recommend it.

Pros: Fits nicely in the hand, brush is large for big dogs

Cons: Expensive, not for small dogs

This has a nice design so yuo can brush dogs teeth without trouble. It can bend a bit but not too much or it will break. the bristles are nice quality for brushing

Pros: easier to use that othes

Cons: when it breaks
