Didn’t care for it
Color: Macrobrush Kit
I really didn’t care for this. The brush is small and the bristles too short. I much prefer a regular toothbrush

Brush head stays put
I prefer to use this than the other ones. Other reviews says the brush head gets disconnected from the holder so far I didn’t have the same experience. I like the 360 brush head. It just takes time for my puppies to get used to it.

Perfect Dog Toothbrush!!
Color: Macrobrush Kit, Color: Macrobrush Kit
As a pet momma of 7 animals, I make sure that all my babies are well taken care of. A lot of people forget about dental!! This toothbrush is so easy to use and has two heads so I can switch heads for my other dog. It has a great handle and I love that the bristles are 360 so they can clean every tooth!! Great for the price and functionalities!! I used it on my two pits and the size was perfect! I got the medium to large breed. The bristles are soft and it’s held up amazingly even with two pits!
