[Help] Ways to keep my dog busy during the day?

I work from home and my mini Australian Shepherd seems to be very bored all the time. I am very lucky because he is NOT the destructive type. He will just continue to try to bring me his toys in attempt to get me to play with him. Sometimes, when I leave my desk I will notice that he has brought me nearly all of his toys from his toy bin. He will bring his rope to me and nudge it up against my leg to get my attention like, "Hey! Come on! Let's play!" Luckily, I am able to interact with him a lot and take him out on walks throughout the day when I take a break. I feel so bad (sometimes I have even thought about getting him a little brother aussie! haha) because I don't want to ignore him but I need to work so I can pay our bills :) Looking for things that can keep him entertained throughout the day! via /r/dogs http://ift.tt/2rxvOBI
