I did this once before on the other dog forum but with a lot of suggestions of what I THINK he might be. Be fun to try again with a bunch of new people and no influence from my opinion yet. Some pictures from our recent beach trip He's about 5.5 years old and around 47#. I can get measurements if I remember tonight. Single coat, 1.5-2 inches in the longest areas, webbed toes. He loves everyone, never met a stranger just future friends. Gets along with most dogs, is a bit too rough and vocal for some dogs though. He'll mostly just ignore small dogs, greet politely but knows he can't play rough with them so doesn't try to play at all. Goes to doggie daycare once, sometimes twice, a week and does great. Huge snuggler, velcro but not needy, on the higher end of moderate energy. Basically on an average day he gets walked 2-3 miles a day and maybe 10-15 minutes of play/training and 1-2 days at daycare. He CAN go all day but doesn't have to. Pretty decent prey drive, wants to chase squirrels and deer, HAS to try and chase chipmunks and rabbits. Neighborhood cats are starting to approach the chipmunk/rabbit level of MUST try and chase. He LOVES doing nosework and is pretty good at it. ETA: Forgot to add he's extremely food motivated. Will work his butt off for kibble let alone high value treats. Teaching him something new is mostly a matter of getting him to understand what it is I want him to do and he's a pretty good problem solver. Pretty biddable in general as well. Example of his idea of fun play, at least 90% of the vocalization is from him. This is also after about four days of this 1 year old foster staying with us and wanting to play constantly if they were together. My boy was tired haha. http://www.youtube.com/watch?v=PPGRZlzccKw He'll always be my snugly brindle mutt but it's fun to get guesses. I'm sure he is the result of at least a couple generations of mutts.
