A bit of basic info.
We currently have a Lab(entire 5yrs) and Bernese(entire 18mnths) living in the house. They get on fine.
My sister has 2 Jacks 1 male(entire 7yrs) and 1 bitch(neutered 5yrs). They used to live with us until she moved out recently.
These Jacks often get thrown into our house when my sister is out, which is a common occurance.
Male Jack was stolen when he was 2yrs old and was missing for 1yr. In that time Female jack came into house.
Male Jack found by Police and returned to us. Male Jack then gets stolen by same lady for second time, missing 6 months. In that time Lab comes into house.
Male Jack is very highly strung. If he is in the house and Lab walks in he will walk up to Lab and growl and sometimes snarl. This has lead to some nasty attacks on the Jack by the Lab who is always gentle natured until pushed too far by the Jack.
Today this all errupted again while i was out of the room. Managed to split them up but the other 2 dogs were trying to get involved as well.
Jack is fine bar a couple of puncture wounds.
Jack also growls at me if i walk up the stairs and he is sitting at the top of them. Often snarling at me. Occasionaly does this to my father as well.
I have paid for and had in 3 different behaviourists. I have followed each ones advice and got no where. my father and sister say there is nothing wrong with the Jack and thats him talking(what the ???)
Jack had bitten me twice when i have been in training with him.
Any ideas of what i can do to alleviate these issues and the fact that neither my sister or father reckon there is a problem...Its frustrating as i dont want the Jack to get hurt anymore, nor do i and i just wish he would calm down, this may assist him in not being so highly strung(or not as the case maybe).
I have recently started squirting water at the Jack when he growls at me which stops him then, but he'll do it the next day etc.
Apologies for the bad spelling and grammer, am very tired.
RIP Bentley - such a wonderful dog to live with, never forgotten.
