Sorry everyone for the late reply,
I have read everyones replies and thankyou all, however Im not sure I can reply to everyone individually
Right, I will try and bullet point things as I find it easyer
-when Jim was biting there was no damage caused and he seems to be rather soft mouthed, fights last/lasted a few seconds and afterwards the dogs both had drool and slobber on them but I think after watching them carefully its a bit of a joint effort as Tully does go back for him
-Today is Saturday, we got Jim last Sunday, so we have had him for 6 days, Monday was terrible, I cried, the day was awful, Tuesday was better, I didnt cry, Wednesday he was the same, Thursday when I posted this he was a little better, however since thursday he has improved so so much, he has come on leaps and bounds, he is sitting back and "leaving it" with his food
he is playing with Tully in the garden for hours and Tully is enjoying his company! He has not made a wee in the house for 24 hours and there has not been a scrap now since yesterday morning, the scrap was over a toy
He has calmed down loads and the difference in him right now is huge compared to Monday.
I am actually enjoying his company today and its very amusing having a dog that cant open the gate latch and walks around wagging his tail and hitting it on everything
-Ok so what I think he is/is feeling
I think he is NOT a bad or nasty dog, he has never been told what manners are, he has been "free-fed" wich is not so good and I have gotten off the breeder he only ever had toys outside
The owners seem to have treated him wrong/harshly and he is full of anxiety in some times hence why he wants to guard something
He has not been socialized enough and he has not been trained
Today I have had him at my parents, he has been told off by the two older dogs and he has settled hugely, Tully and Jim have been walking around together all day and playing in the garden and having a lovely time.
Right so thats what has happened on that side of things
On the breeder side of things, I asked for half the money back upfront and the rest over a month on friday, she has got back to me today saying actually no she does not want Jim back as she doesnt have the money.
Today after taking Jim out with Tully, Tully got out of the car in a public car park! which is absolutely amazing! he was looking at Jim and following lead, he then walked around town with no shaking or panicking or leaping or anything! it was such a shock, I never in a million years expected that
Yes if we think it would change things we would get Jim chopped, but with all of our other dogs and my parents foster dogs it has never made a behavioral difference so I would be hesitant doing this
So..... seeing as Jim HAS improved over the last 6 days and yes I was not expecting it but then again Tully had hangups when I got him, just of the nervous kind, if I put into this giant puppy and he is giving back already then there is no reason why I cannot try and keep this puppy and do the best I can for him
Thankyou all and I will try and keep you posted
Thankyou OldShep yes I agree with your post, he has stopped weeing over this last 24hours and I think he is feeling more secure

and thankyou very much, Thankyou also Sally, very nice post, Thankyou everyone else
Yes perhaps I did get a dog too soon after Laddie leaving us, but I think Jim is happier here and I think I can give him a lovely life, also I am very happy with how Tully is over the last day or two
Thankyou again
