I'm still considering getting rid of Hector and he's 2.
(not really, I'm just kidding...but I know how you felt when it comes to a difficult dog!)
The rowdy dogs:
Hector-2 y/o GSD (mix?) rescue
Scooter-12 y/o ACD/Border Collie mix
Bandit-8 y/o ACD
Wooby-14 y/o ACD
Abutiu "Abi"-ACD puppy and hopeful future SAR dog!
