The RSPCA recommends that you do not purchase a dog from markets or places where large numbers of dogs are kept for sale. Dogs sold from these establishments are very rarely examined by a veterinarian, and therefore may not be entirely healthy. Never purchase a puppy that looks unwell and if you are concerned about the welfare of the animal, contact the RSPCA Inspectorate.
To be a successful pet shop owner, manager or employee, you need to be able to sell merchandise, from pet food and toys to cages, fish tanks, leashes and the pets themselves. Obviously you need to know about caring for different animals in order to keep the animals you are selling in good condition; and advise customers on the products they might buy. Some pet shops may be more caring for the animals than others.
