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 agree with the others that although he seems to have Basenji in him - his head is def. not Basenji.
As for the leg I'd have it amputated if it troubles him - He'll cope with 3 legs I'm sure, but certainly consult a specialist first. Please keep us updated.
Put a bell on his collar. :)
Ours will start a 500, or bring us a ball to throw… or they start wrestling with each other. During nice weather, we take them outside. Helps A LOT.
Thank you very much for the info. I will have to try the time out. He was crate trained as far as being house broken, but now when I put brownie in the crate all he does is whine.. I do have 2 older dogs. one that plays with him and the other, well he just growls at brownie. The mother that was there when I got Brownie was a white shepard, maybe that is where the broad nose comes in.
