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!

My favorite toothbrush for my fur babies!
Color: Pink (2-pack)
I think these brushes are the easiest way to brush your fur babies teeth. I can get into their mouths and really see in there and brush each tooth and make sure the tarter is off. They even assist by trying to bite the brush and I use toothpaste for dog and gently brush back and forth first the front teeth then the side teeth then the inside teeth and the top of the teeth then the inside of the bottom and top teeth and I end with the left inside top and bottom teeth. I use vanilla mint toothpaste for dogs because my dogs are allergic to proteins. Their teeth look so white and their vet comments that their teeth look so great and clean. She does want them of course to have their yearly cleaning but she said there is no rush because their teeth are so clean and she sees no dental disease. I make sure that I wash the brushes daily with soap and keep them open after use otherwise mold will grow on them if you shut them in the case they come in. My pups weigh 6 lbs and 7 lbs and are Maltese females. They cooperate fully with me brushing their teeth because I started when they were puppies and now they are one and two years old. These brushes are lightweight and not expensive at all. I usually buy several at a time to make sure I have clean ones on hand just like you would change a human toothbrush monthly. Each pup gets its own toothbrush and I label the case for each with a marker. I like these better than a regular toothbrush because it’s 360 degrees and the pup can chew on it without hurting themselves or the bristles coming off. Highly recommend!

Dog Approved - Highly Preferred Over Standard Toothbrush
Color: Neon (4-pack)
These pet finger tooth brushes work well for me and my dog. He most definitely tolerates these so much more than a standard tooth brush. I believe I am able to reach more of his teeth and that I'm more effective brushing with these than I am with a standard brush. I put one on each of my index fingers. This makes it easier to do each side and the top and bottom without having to twist and turn to reach everything. The size is just right for my index fingers. They are a little tight getting them on and I have found that wetting my finger and the inside of the finger brush makes it a lot easier to put them on. The bristles on the finger brushes are soft, yet they are durable enough to give some good scrub quality and gum massage. These are a good price for what you get. I purchased the four-pack at right about $16.00. I have gotten numerous uses so far out of the two that I have been using. I will definitely purchase these again when it is time.
