We don't have a Petco here. But we do have the new PetSmart, with vet, groomer etc. Once a month we all go and stock up on food, treats, "toy of the month" (week, really!) and something new like a bed, collar, leash. I also have to stock up for my two kittys and guinea pig! We usually have two carts and the check out lady thinks we're a little nutz!! Does Sadie go with you? Star trys to clean out the cookie aisle every time. I didn't know you had a dog walking service. That's great! You sound like a very dedicated young woman and true animal lover!!! STILL WAITING for the debut of sweet Sadie! Glad you had fun shopping for your girl! Give her a big hug and kiss from me and Star!!
