Well, first off, I did not get Neek as a puppy. He was almost 4 yr old and about 90# GSD when we brought him home.
I do work with him alot, we are very bonded but he is just stubborn about things he doesnt want to do. I had no choice with his nails, I had tried and tried, held his paws, tried to get him used to that and it went on for weeks....I had no choice. yes, at one point he had my whole hand in his mouth. He has a soft mouth but i think it was his way of telling me: I dont like this!
Im not sure if I could pick him up nd put him in tub, he is big boy. And also, since GSD's have sensitive skin I dont like to bathe him too much, maybe twice a yr would be good. He itches alot, not sure what thats about.
He loves to eatpeople food, so that is why I bring treats in. Its how i taught my other GSD, Sash to take baths. He was a breeze compared to Neek. I could cut his nails, give him baths, etc but I got him as a puppy ad started young. The rescue dog is a whole different story. When we got hm he smelled very good, like he had just had a bath and his nails weree short. Im not sure if his former owners too him to groomers.
I will use some of your suggestions and see how it works. thanks!
