Duke is a one person dog. He is not people aggressive but is food aggressive.. We love duke but can not keep him. Duke did grow up with a cat but has not been around one for awhile. My son had duke from a puppy but then got married and had kids and duke is not good with the kids. My son is heart broken to let Duke go but Duke is alone most of the time. He has to be kept away from the babies so he ends up in a room alone or out side alone. To make things worse they have to move to an apartment and no one will rent to them with a big dog, If the right person wants to adopt Duke you could come visit him and get to know him before you take him home. He really is a lovable dog.
