What types of dogs are suited to the low & high angle dumbbells? Do the medium angle ones suit most dogs?
Every once in a while we have an issue with picking it up from one of the balls, not the stem, and my OB instructor said that a properly fitted one would help solve the problem. I've been so lazy though...
According to Max200, the high angle is for long nosed dogs like borzoi, GSD, collie, etc.
The low angle is for short nosed dogs like pugs, shitzu, etc so the ends don't interfere with their cheeks, eyes, or vision.
There are also some that are higher or lower to the ground, which is a different thing. Maybe you need one that is higher off the ground?
