Every time my husband gets up from the sofa my castrated male dog grabs hold of him barks and starts to hump his arm. He doesn't do it with me or my daughter and our other dog (a female) doesn't do it she just joins in the barking because she loves the sound of her own voice. Is my dog trying to control my husband and how do we stop this behaviour?

I doubt it's control, but some form of possessive behaviour yes, I'd recommend a behaviourist if its an issue. Stopping it will revolve around distracting him and praising the good behaviour, but you need to work out the source really, diverting it won't do any good if its a behaviour that needs to be performed. Have you had him since a pup? How old is he? What age was he castrated?

He is a JR/Patterdale terrier,we have had him from a puppy, he was castrated as soon as he was old enough and he is now 5 yrs old. My husband just shakes him off and ignores the behaviour but I think we now need to address the problem, I just don't know where to start. He is very territorial and gets aggressive when strangers come to the house.

definatley sounds likes he's got some dominance issues (not in a pack sense, but more in a stroppy little dog sense) and is pretty protective - both things you need to sort really, as you don't want them escalating.

I'd recommend a behaviourist if you can afford it, if not look up victoria still well on you tube (its me or the dog) she's dealt with many of these types of situations in her programmes and there may be some good advice on there. Most importantly - no telling him off, don't get stressed (easier said than done) and reward the good behaviour.

Kikopup has numerous videos and luckily they are all using positive training methods. Also have a look there on using a house line. You don't have to hold it like a lead but you can put your foot on it so that the dog can't do this. If you can teach a good settle and reward him for not jumping up that would help a lot.

Does your husband play lots of games with the dog - I just wondered if your dog is overstimulated by play and sees your husband as his bestie mate in the world and wants to play. If the dog has no boundaries in the house or rules in games then he could be too hyper and not realise he can and should settle down.

I've also found this website so helpful for resources too. The DVD's are really useful.

We have noticed with our dog he gets excited when we have guests round and as soon as the guests leave he humps my partners leg then runs around the room like a loony! If he cant get to my partner he occasionally grabs me but he needs both my legs because ones too skinny for him.

Dont know why he does it but once hes humped and run round the room he settles down straight away and back to normal.

Thanks for the links shadow27 will look later as I am on my way to work now.
