Sit on him.
Mine don't like it, but they will let me do it. In the beginning...it was a real job to hold a squirming dog and try to clip their nails. Nail trimming would take me 15 minutes...because of them fighting me. I did it any way...eventually they just realized....their nails were going to be trimmed....AND that afterward there would be TREATS. It takes less than 5 minutes. If I do Ramsey's first....the minute I set her down...she is demanding the treat. I let you do it where's the dang treat.
Oh yeah...I do not let them see I have the clippers before hand either.
