Thank you for submitting your question regarding Mike. This can be a hardy breed combination. The biggest problem I tend to see is joint disease (mainly arthritis) due to large size of these dogs. This can occur as the dog ages. Keeping the dog very lean throughout its life will help to protect the joints. The other big issue is that some of these dogs can be aggressive. So I think proper socialization and obedience training starting as pups is important. This helps to form a well adjusted dog. Most of them that j see are very sweet. I hope this information helps!
