His name is Phineas. He is a 6-7 month old shelter dog, I got him when he was just about 8-10 weeks old. If he is part Dobie (I'll try to have the DNA test), he'd be my second dobie mix. I had a female Catahoula/Doberman who mix passed away in February from lymphoma. She was an amazing dog. He's my first male dog and so far he is MUCH different from the female mix. She was more serious. He is incredibly goofy.
I wasn't sure about the Dobie part, but the hound is evident in the jowls. His bark reminds me of my former dog and so do his eyes, which is why I thought he might be Doberman. I have heard Rottie, but he's very slight.
Thanks for all the guesses...we'll see what he looks like when he grows up. So far he's all boy (think of 4 year old boys getting into everything...).
