Flimsy and snapped easily
Style: Big Dog, Size: 1 Count (Pack of 1)
Snapped in literally under a minute of using it. The toothbrush head is so small and the handle is really thin and flimsy even though it’s advertised for large dogs… I’m so disappointed.

does the job
Style: Medium Dog, Size: 1 Count (Pack of 1)
Its does the job of cleaning my dachshunds teeth. The only issue is that the SMALL and MEDIUM are the same size. Small was okay but wanted something that would cover more area. Picked up the Medium and they are basicly if not the same size....

It’s an okay toothbrush
Style: Big Dog, Size: 1 Count (Pack of 1)
I thought this design was very unique and a great idea when I bought the toothbrush. The handle is sort of harder to hold on to. I like how the toothbrush bristles are very soft and it is flat on the end to prevent back of the mouth injuries.
