I feel your pain with the walks.
I try to avoid walking past the houses with dogs and when I see another person with a dog...I go the opposite direction. Izzy will bark like someone is strangling him! Its so loud and dramatic! Ive tried making him sit and telling him "no bark". But he is so focused he doesnt listen. I am going to try to take treats with me next time. Do they ever grow out of this? Other than that he is a sweetheart!
