We adopted a dog that was pretty close to feral. He will not let us pet him, and we have to crate him in order to brush his long hair - I get in the crate with him. I have to move slowly since he is so scared. What would be the best way to cut his nails? Noticed last night they are really long - (he has hair between his toes so he was standing in just the right position for us to see) and I really need to cut them. Would appreciate any ideas.
