His condition could very well be result of being alone and on the run for a while longer than you may have first thought.
Please try to find his family first. I had one of my Show dogs run away once, without a collar, it was the "art work" of my brother in law, who adores the dogs but is so distracted. I am so glad my neighbor knew my dog and the and the animal officer who picked him up , 3 blocks away from my home , when another neighbor saw him "flirting" with every pretty girl who passed on a BUSY street ! This was years ago when we first bought this house and before we had puppy proofed our yard and driveway entrance and side entrance...
You can be right and he may have had a bad family, but also he may have a family that may be looking for him ...
I am forever grateful to my neighbor !!! FOREVER !!!!
I am glad to see in the posts here that other people share the same thoughts i had at first ... that maybe he is shaggi from being out so long !
Good luck anyways !
XOXO
