Roscoe is a BullMastiff. He's 7month 2 weeks old now. He is a very smart, sweet little pup. He is not quiet as some have described this breed. He barks ( talks) to me a lot. Letting me know when he's hungry or has to potty or just board. He did potty train quickly. By 4months! Amazing, loving, smart & expressive face and voice.
Great looking pup. Just keep up with socialization and training. Between 8 months and 1 year he will come into his true temperament. Not sure which breed descriptions you have read, but there generally very loving with there family and always want to be around them.
