Hi all
It is my dog that Bundys_mum is talking about. The problem is not so much the cost of getting out another trainer, but the fact that I can't afford to get out another trainer and NOT solve the problem. If I have no luck in making some progress myself in the next week or so I will definitely seek further professional help, but being that I am a student and just forked out an entire week's wage to get a trainer out not just once but twice, to solve the problem to no avail, I'm not keen to do the same again right away. I believe the problem has worsened of late as I have followed the advice of the trainer and tried to reassert the pack hierarchy.
I have been working on the triangle of temptation, which he does perfectly. He won't actually take the bone without me saying so, but once he has it I cannot approach him without a growl. Fortunately we don't have any young children around, but that is exactly why I am trying to solve this problem, I 100% agree with Bundys_mum that is is not acceptable.
We did not just leave him to eat as a puppy, we did try to practise removing his food and he was fine. The problem is only with bones and as I got him as a 16yo, I never thought of the possible consequences of this possessiveness and stupidly did not practice doing the same with bones. Also, before anyone asks, he goes to obedience training, did puppy preschool, is socialized etc, we sincerely tried to do all the right things with him.
