I just ordered this tool last week and followed the tips of others (getting my dog used to the noise, giving her treats, only working for very short periods). Of course, the treats were "scarfed down" very quickly and then she wanted to quit.The solution!! I lined a bowl with peanut butter! Not much, just enough to keep her busy for awhile. It allowed me to work longer & she didn't even care that I was playing with her feet. When the bowl was cleaned, we were both ready to quit. I'll do this every few days until her nails are perfectly trimmed.Hope this works for you, too.
