Last evening we were able to exhaust both the dogs. It only takes 1 hour at the Dog Park and 30 minutes in PetSmart. It took me about 20 minutes to evaluate all the chew toys and try and figure out which ones may last 20 minutes (one she seems to like, one she doesn't)! I also had to get her tag made. She now has doggie jewellery (they don’t cell the plan tin ones anymore). This one actually has Swarovksi Crystals. After dinner, both dogs were tired out! Poor Gemi is exhausted. 2 hours of exercise a day is more than she needs and is use to.
