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.
Safety is also a consideration. In September 2018 the US Food and Drug Administration (FDA) released a statement warning about the risk of tremors and seizures in animals treated with products containing drugs in the isoxazoline class, which are used to combat fleas and ticks. However, the FDA said it still considers the products "safe and effective".
If dogs live indoors they need to be provided with a dog bed. Most dogs though are hardy enough to sleep outdoors in a well-built, well-furnished and weatherproof kennel. The kennel should be warm, dry and draught free, elevated from the ground, near the house and human activity but not in a thoroughfare. It should be protected from rain and excessive sun, and the bedding should be changed regularly. Washable rugs, cushions or blankets are suitable as bedding.
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.
