Well he arrived yesterday and I have incorporated some of the suggestions.
-he is being fed in his crate
-he is stubborn and a land-shark but actually seems quite submissive thus far
-he hates his crate
-he desperately wants to run
-he is food motivated but displays little prey drive
-he is very thin and seems to lack any muscle mass I was told he was spending the majority of his time in his crate as the sharkiness escalated.
-he is not a very bold pup and not the worst I have seen regarding shy/fearfulness
The dogs have mingled but have met...I am waiting a few days until I sense a nonchalance about each others presence. There were some growls but nothing serious nor something that put me on edge. Milo (my four year old) is happily distracted by play. The pup is barky but I did see a play bow...so I think (hope) it will be ok. They were walked together this morning in the back fields and the pup was walked independently this evening. Leash manners need improvement for both of them.
I have decided to feed him in his crate as suggested. I think this will avoid problems between the dogs should any exist and hopefully change the pup's attitude towards his crate. It is not easy getting him in there. I have also stocked up on crate safe and inviting chew toys that are strictly crate treats.
He knows sit well and I have been working on down.
I have not experienced a bad episode of the nips yet, but have been nipped though just gently. I would suggest more mouthiness. He was told no. If he hurts me I intend to shut down on him. Turn my back and refuse to interact. I know this won't be a great way to handle it until we have bonded a bit, but I prefer to let them teach themselves if I can figure out how. I have a rope toy that did not interest him so I turned it into a snake. This he likes. He was rewarded any time he bites down on it. We had a few gentle, happy games of tug and when I told him to drop it, he was rewarded for doing so. Quite frankly he was not reacting to my command, he really sucks at toy play, but reward good behavior as the saying goes. My thinking is the rope game thing addresses resource guarding, biting and provides play/bonding time all in one.
I decided to interact with him and he is friendly and definitely wanted too. I know that his authentic self might be hiding on me right now, he has only been here 24 hours but if that is so, I wanted to take advantage of it.
Please let me know if you think I am inadvertently making any errors.
I know that sometimes a prong collar is a must but I have never used one. This pup had one being used on him at the recommendation of the first owner's trainer. Apparently it was so tight it was difficult to remove. This information comes from owner number two. I was aware that he was in one when I visited but never checked it and frankly know nothing about them. Is it possible that the prong collar was increasing the anxiety of the pup and creating a lot of the biting issues? That and the fact that he was being so tough to handle that his exercise was increasingly limited?
I now have contact info on the vaccination papers for the original breeder. I hoping to find out exactly what this pup is....will post a picture when I can
Thanks for your help.
