Please can people help. I have a 5.5 month old puppy who when in the stacked position becomes snappy towards people going over him. He is ok when people come into the house, he is fine when I am out on walks and people touch him, but as soon as I have him in a stand position and then someone was to start goining over him he will snap, his whole body language changes. I can touch him all over and he is getting better with the members of the family. He is not dog aggressive, if anything he is the only dog that I have that gets on with all the other dogs and dogs outside his PAC, and wants to be with me all the time. I am a little confused by him and need some help as he is a fantastic looking dog and want to start showing him :)

He's scared so don't push it as you could end up making things a lot worse. Forget about showing him for the time being, if he's like this at home and out at familiar places, then it will be ten times worse in unfamiliar places. Get people (ringcraft is an ideal place IF the trainers listen to what you ask of them) to ONLY offer him treats when you stand him, without even trying to touch him, and work like that for a few weeks, then gradually move on very slowly until he feels confident enough to be touched.

I think in some breeds pups are shown too young as many need to mature more, and if a puppy has a bad experience (i.e. gets scared at a show) it is MUCH harder to get over than if an adult has a bad experience, so please take it slowly. I've made that mistake myself!

I am not sure why he is like it, I will leave off with the show training for a while, I was going to try obedience with him as he listens to me I was hoping that I can teach him the word "touch" and get people to touch him as I say it and they give him a treat, he may realise it is a positive being touched. What do you think? He want like this as a tiny puppy, I got him at 15wks and he was ok so don't know what changed him :(

I think if you do that, given he is already uncomfortable, the cue 'touch' will just come to mean 'something you don't like is about to happen'.

I would forget stacking him for now, get him happy around people, happy to ask people for physical contact, but do NOT have people bribe him or trick him into physical contact.

Stick with getting him comfortable in a variety of locations (home, outside, ringcraft), and getting him happy about inviting people to touch him but NOT when stacked.

If needs be you can enter some open shows when hes old enough, and just ask before hand that the judge doesn't go over him, hes just there for the experience of the ring and standing in it.

I would not have got a puppy at 15wks, since it increases the chances of problems which are a result of inadequate socialisation (like this one).

I'd suggest you enrol him in a good puppy class, which includes handling - at the puppy's own pace - and see if the trainer there can help you.  I wouldn't be looking for a formal 'obedience' class, as that's unlikely to help - you need something slow-paced and with the focus equally on the development of the puppies.  Try www.puppyschool.co.uk

what breed is he?

He is an Akita

The only reason I got him at 15wks is because he is an import so needed to wait until he had had all his injections etc

Has anything happened to him that might have hurt him?  Bashed himself, maybe an awkward turn?  I know he's only young but we all know how crazy puppies can be, I'm wondering if putting him in the stack position is putting pressure somewhere that's hurting him (although it's not an extreme position or anything, it's still slightly exaggerated from normal so him standing in it for more than a moment could just be tweaking something).

Have a look at TTouch - I've recently heard fantastic things about a dog with severe pain who in just a couple of days went from major aggression to anyone trying to touch him to allowing complete strangers to fuss him all over, well worth a look for this little guy I think.
