Have only just caught up with this. Sorry to read you are having problems with Hamish Shona
I agree about the castration.
The only thing I will say is, that, the dog I told you about before in the previous thread about Indie and Hamish fighting was castrasted and still showed similiar behaviour to Hamish is showing, including the biting but his problems run very deep, so I guess what I'm trying to say is maybe castration isn't always the answer although for Hamish it could be, its gotta be worth a try I think though.
You can borrow Nance if you like
, she has an UNCANNY way of putting dogs in their place, Milo and stud dogs alike, she's not picky!! One word from her and thats them told as small as she is!
Seriously though its a difficult one Shona, I really feel for you. Sending you and the dogs lots of love
Good Luck xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
