I'm keeping an eye out in my local shelter for that one special dog, but i'm not a high energy person. I love newfies and want one of my own but i'm concerned about the health problems associated with the breed. I get very sad seeing a pet suffering, even if i do the best i can to help. So i was looking into mixed breeds, and i was wondering if there are any particular breeds who may cover some of the weaknesses of the Newfie breed? What should i be looking for, in the event i don't find one in a shelter?
