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.
The rescue girl who would get out of the invisible fence and had a high prey drive also had a thing for a bull. She was lure coursing near Ft. Worth TX and the field was near where the cattle was fenced in at. She went crazy and wanted to go after this huge steer/bull through the fence. I believe it was a TX Longhorn. One kick from him and she would have been history!
