Right, so my dog(not a puppy) has suddently become very overprotective of a toy I bought him last week, he didnt really care that much about it untill earlier today where he suddently took it outside(into the garden) and just walked around digging a hole, dropping it to hide it, afterwards he just stood there looking for good 10-15 seconds & decided that it shouldnt be dug down right there so he took it somewhere else to dig it down, is this normal? Ive only had him for a few weeks(got him from a shelter) and I'm not sure who the owner was and if he did anything wrong, am I just overreacting or is there something wrong? My friends dog has never done this even though they're the same breed.
