Hello! I sympathize with you! I have been agonizing over a first nail trim for my 4 month old Shadow who is also not yet spayed! I have read and watched several videos- which just made me really nervous. However, I did learn a few useful things which helped me successfully trim Shadow’s nails today! First- I brought her into the bathroom, where she had never been before, and sat down in the floor with her on my lap. I had her back against my chest, with my hand under her front paws, supporting her chest. I used toenail clippers- so much easier to handle at this point! Next, treats! I gave Shadow a piece if raisin, banana it papaya (small pieces) whenever she started to move around. I had her front paws done within a few minutes! The back paws were hard to do on my own, but my daughter held her in the same position, and there was no struggle. It went surprisingly well… Hope it helps!
