Hi, we have two cockers, a 6 year old bitch (Lucy) and an 11 month old dog (Jarvis). Jarvis is a working cocker and is entire.
The problem is that Jarvis has started to show aggression, usually towards Lucy and it is generally to do with food. If he thinks that she has food and he doesn't, he will sometimes attack her. It generally happens after they have eaten and she maybe has traces of food around her mouth or her ears.
We immediately separate them and he is sent to his crate. He knows he has done wrong as he attempts to go to his basket rather than be put in the crate. If we then attempt to drag him out of the basket he sometimes growls or attempts to bite us.
My partner is understandably getting a little afraid and wants to castrate him, believing it will solve the problem.
I do not want to castrate him, preferring to take a behavioural approach.
I'd be grateful for any advice you can give, and also any recommendations for good dog behaviourists/trainers in the Aberdeenshire area.
Many thanks!
