Yes I do clip my dogs toenails. I bought a good set of clippers at Petco. I am not sure of the brand, but they have a plate behind the hole to stick their toenail in that keeps you from going too short. I dont clip them as often as I should so sometimes will have to clip the same toenail more than once.
If you do happen to cut into the quick, to where it bleeds, dab a drop of SUPER GLUE on it. Blow on it till it dries. Will stop the bleeding.
One thing I found out, is when I clip her nails, if she is in "HER' swivel recliner, like she is most the time, if I turn her on her back with her head toward me she will let me hold her feet and clip her nails much better than if she is upright. She doesn't try to pull back as much. Don't know why, but it works for me!
