This breed is a very large. They are very observant of everything They have super sonic like hearing up to a mile. They bark very loudly when they are trying to alert you to something out of the ordinary We have two cats and he is always exerting himself as an Alpha male and tormenting them. We have horses and other barn animals that he enjoys being with and is very congenial with them At this point he is still chewing everything in site and hopefully that abates when all permanent teeth are in. After having several large Golden Retrievers in the past he seems to be a much more muscular and headstrong dog.
