I would really welcome some advice. I have posted on here a couple of times over the last few weeks about our gsd puppy. I am pleased to say that in many areas (on the lead, in the car, in the crate and housetraining) things are really progressing. We have got through that "oh my god what have we done?" phase and come out the other side and for a lot of the time he is a lovely companion.
Now on to the not so good bit... all the time DP is in the house, pup is wonderfully behaved. he listens, is calm, just generally nice to have around.
As soon as DP leaves for work in the morning pup becomes extremely high maintenence (I know this is part of being a pup but I still need a solution to manage it). His mouthing, nipping and chewing goes out of control. He runs like a maniac from room to room- will not listen, sit, lie- any of the things he does with DP in the house. He listens to me with DP around but will not listen when he is not.
I try to ignore as much of the 'naughty' behaviour as I can as I have been told to do and then reward the good. The result is, he doesn't care that he is ignored. in fact, when he is put in another room he immediately damages something.
Sometimes, I can't just ignore things-e.g he runs off wih DD best coat- so I say 'leave' and give him a treat when he does 'leave' the item. Now, he purposely takes things and then looks to me for a reward.Not really the idea I had in mind.
With regards to the mouthing- when you try and stroke his head, his mouth is immediately open whipping his head around to try and get hold of someone's clothes or hands. If the person ignores the behaviour and turns round, pup will do what appears to be a retalitory nip on the thigh for example.
He goes to puppy training, has good exercise in the day and is doing well in other repects.
I expect people may think that the only reason he is so 'good' in the evening with DP is because he is tired. Not the case- there have been several evenings where dp has been out til late and pup has behaved really badly all up until my bedtime.
Any advice much appreciated!!
