He looks more mature than what he is! Jasper is approx. 4 years old, a tall, lanky fellow who is starting to gain weight with the ridiculous amount of food we're feeding him! We're not sure on breed .. perhaps Anatoly? He is people-friendly, kid-friendly and enjoys a good romp with another dog (although we've never had him with small breeds). Cats are not likely for him, and he does need work on leash as he's super strong and probably hasn't had a lot of prior leash work. He's a quiet dog so when he barks, we pay attention!
