Louie is now 2 and a half and has always had this "side" to him whereby he gets quite aggressive (to varying degrees) when trying to take things from him or making him do things he does not want to do.
He sees my wife as the leader of the house it appears but I bear the brunt of these moments and have many cuts and grazes accross my fingers, knuckles and arms to prove it. Bearing in mind that take him for nearly all of his walks, feed him most days and play with him this is quite difficult to take and upsetting to be honest.
In the early days, he used to snap when I tried to take, for example socks off him (he would run under the bed or table with them), things he perhaps may have stolen from the bin, went near him while he was eating and even snapped if we nudged him off the sofa.
As time went on, we saw a lady a few times at our vet who dealt with behavious problems and certain things improved. She said it looked like he maybe was going to have this possessiveness in him always but the trick would be to avoid these confrontations.
1) Sofa - although he jumps up when we are not around he soons get down when we are back
2) I can now easily take his food away from him while he eats on command and he even looks at me to ask permission to start when I put it down.
3) I can throw his toys for him and he brings them back if I have a treat and begrudgingly drops them. If I do not have a treat, his idea of playing is parading up and down in front of us with a toy in his mouth as if to say "go on, try and take this off me". If anyone moves their hand anywhere near him, he moves his head away, walks off then does it again. He loves the fact that we cannot get it off him so we do not even attempt to take stuff from him (even though I would love to play tug-o-war with him).
4) I can make him sit and wait for however long I want as long as I have a treat in my hand (he always did this perfectly at puppy class).
These are the positive things (they seem positive to me anyway) and the fact that we know what sort of thing makes him turn.
The worst examples are probably as follows:
a) One time he had dragged something out of the bin in the kitchen (something horrible like a few teabags or a nappy bag), I walked in noticed, got a treat and tried to lure him out of the room (if I so much as call him name he growls), he had to really think about whether it was worth coming out for the treat, I placed a treat in a corner of the lounge (far enough away so that I can retrieve rubbish while he is away), he slowly walks past to get to treat and as I walk the other way to retrieve rubbish, he twigged what I was doing and absolutely went berserk. He leapt up and was snapping and snarling leaving holes in my clothes and a couple of cuts on my hands. He really means it when he turns and so I just turn my back and walk away as i know full if I lose my temper and raise my voice to him, he will get even more aggressive.
2) Another was Xmas day morning, there is lots of wrapping paper strewn accross the floor, I am walking around picking it up, I get to the last bit and just I bend down to get it, he decides he wants it and tries to take it. I tell him "no" and try to take it from him, he loses it again and properly clamps his teeth down onto my hand and I have to wait for him to let go to remove my hand. My wife steps in to put him in the kitchen for misbehaving, as soon as her hand goes near him, she gets the same treatment, he was so angry, he had to lifted off the floor and forcibly put in the kitchen. He is literally like a different dog when this happens and a couple of mins later, he is good as gold again (he does act sheepish though as if he knows he has done wrong).
I am sorry if I have rambled on a bit, I am just trying to give some examples of what triggers him and what we have tried. I have also been reading a book called "Mine" recommended on these forums but I agree with what someone else said on another aggression thread, I do find the book very hard to follow and more aimed at dog trainers rather than owners.
We have taken steps to help resolve this by locking him in the kitchen from time to time (particularly when we are eating) to reinforce the fact that he is not in charge, never have any bins/bin liners near him as him with stuff from the bin have caused the worst episodes and I am now examining him every day like a vet would which I have read is good to reinforce the whole "pack order" rule. I can examine his ears ok, his teeth but as soon as I get to the paws or until his tail, he tries to bite me and/or rolls onto his back mouthing at me.
Anyway, my wife and I can try to resolve this issue (if there is anything else we can do?) but we have a 14 month old daughter. Clearly, she will not have a clue the best way to deal with him (he has not shown any aggresssion toward her thus far, just a couple of tiny grumbles if she is sleeping and she goes and wakes him up). We cannot take the risk of him ever attacking her but so far it is mainly me that he goes for so far. The breeder we bought him from suggested a behaviour specialist but we really do not the money to afford one of these as they are very expensive. Our last resort is of course to rehome him but the idea of this upsets me greatly. People ask me how I feel when he bites me and yes, at the time, of course I am angry but it doesn't make me love him any less.
Can anyone offer any encouragement, advice, anything we have not tried, anything to help us out ? It would be appreciated so much (sorry this post is so long).
