Male dogs are often quite independent and can be a little more difficult to train and control. Males also tend to wander and fight other dogs. Female dogs are more popular as family pets and may cost a little more. By nature females are affectionate and companionable, but unless desexed, will attract male dogs when in season and may reproduce every six months.
If you are not home during the day, your dog should be kept secure in a dog-proof fenced yard and should never be left unsupervised when tethered. In the case of larger properties where this is not possible, then an appropriately fenced dog-run should be constructed, and the dog kennel, along with a plentiful supply of fresh water, should be placed within the run.
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.
