Hopefully things will improve soon and Tristan will grow up to be a fine and strong dog, which everbody here wishes would happen.
Being a small pup now he will probably forget his early days with you, but I'm sure he will always remember the feeling that his "pack" protected him when he was in need. Wolfdogs, like wolves, are very loyal and grateful.
We experienced this with Tina... rescued and adopted her when she was a little puppy and for the following 14 years she'd follow us even into fire...

Now she's very old and sick

, and we're struggling for her again!
