The dog needs a bath

Scott has probably gained about 8 lbs. since we got him. Every time Mikey is in his highchair Scott sits right there next to it waiting to gobble up anything Mikey drops or throws. The dog will eat pretty much anything. Since he does this he often gets food dropped or thrown on top of him. We have found taco meat stuck in his fur, chicken nugget pieces, bread.... He's got a glob of dried yogurt stuck in his fur right now. That happened yesterday and I haven't had a chance to bathe him yet. Scott is starting to get pretty fat. I used to take him on regular walks but since they've been working on our street I haven't been doing that. I don't want him tracking dirt and mud in the house. Once the street construction is done, Scott needs to start exercising and loose some of that gut.
