I recently just changed to second shift and I am also a full time student, so I leave early in the morning and usually don't come home till after 10 at night. My wife gets home after 5 and there is no issue when she gets home. I will get home and the dogs get super excited, the smaller dog will violently attack the bigger dog whether I give them attention or not. It seems to be random. We have a dog door with a back yard. They run around and play and they are fine.
I have been trying to play with them more in my limited free time and take them on more walks thinking that maybe being pent up alone more often may be causing the problem, but nothing has helped. I've done some reading and most of it points at just training the dogs in a general way. Is there anything specific I can do for the dogs for this situation?
