Recently it's been raining and my 9 month old dog (Shepard mix, medium size, about 60 pounds) doesn't go out much (only to use the restroom) because of it. I would want to take him for a walk, but I'm afraid that I might get him sick. We don't have much room for him to roam around, and he usually stays in the living room and the kitchen. Recently though, he would be sleeping, and then around 1am he'll wake up, and decide that it's time to play. He gets really hyper (he starts to jump on me when I'm on the computer) and then he'll start to tug my shirt. He hasn't done these things since he was 4 months old, which is really worrying me. He then gets REALLY aggressive and gets scared of any movement I make (he does the bow pose, like when a dog stretches after sleeping). Although I'm no dog expert, I'm assuming it's because of the lack of exercise. I don't know what kind of activities we can do with him since it's been raining constently. Any ideas or suggesstions (for any of the problems I've listed)? Thanks.
