i was thinking if i should clip my MinPin's nails by myelf, because he hates the groomer to touch him, they have to put a muzzle on him. hes a little monster!! i wanna buy nail clippers, but his nails are black and i dont want to cut his veins...if he had white nails, it would be easy. should i just stick with the groomer? or is there a way u can tell how far u can cut???
