Here are some pics of my boy, he'll be 5 months in 2 weeks. He's been doing great and has improved amazingly in every single aspect of his behavior. The first 2 pics were taken the night we got him, the last 2 were taken yesterday.
No idea, sometimes with mixes it's so hard to tell what the parentage is. I do think that your dog's head is a bit more refined than many of the pit mixes i've seen.
i think hes just trying to flaunt his ridiculously long toe nails.. he gets angry when we try to clip em. we gotta muzzle him and take him to the vet to do it.. haha what a little pain in the butt :p he is my little boy though:D
