Our little guy is growing up and is now 4 months old and 40 pounds.
We thought he might be a Mastiff mix, possibly with Great Dane, known as a Daniff. After searching for different red dog breeds, we found one that looks very close: a Red Alabama Black Mouth Cur. Does anyone have experience with this breed and can verify?
