Inconsistency gives the dog mixed signals and leads to confusion. Never bathe your hamster. Hamsters clean themselves. If you think your hamster smells, the odor is probably coming from dirty bedding. Clean the hamster cage more often.
Dogs are great companions for runners, and they offer visible security.
Plus, regular exercise is the best way to promote your dog's fitness and keep their weight in check. And yours too. Avoid buying new arrival fishes at the pet shop. The first few days after the fish are delivered to the pet store are when their mortality rate is highest, so wait a bit before making your purchase. Scold your dog every time she makes a mistake.
