I am looking forward to all your knowledge, tips and tricks! I recently lost my dogs due to old age and decided that I wanted to foster. I have never owned a GSD and now I am fostering one. We are 3 weeks in now and everything has gone really well, better than expected that's for sure. He was an extreme cruelty case, 8 yrs on a 5'chain, in a vacant lot, guarding some machinery... 24/7/365 ... can you imagine? I want to make sure I do the right thing for him and teach him manners so he can spend his senior years with peace, love and comfort. How do you teach an elderly dog manners? His nose is in overdrive and he can be somewhat of a bully when he wants to "check a person" out.
