Pedigree or purebred dogs are more expensive to buy if purchased from a breeder and their nature and appearance is generally predictable (as they should conform to a breed standard). Crossbreeds (or 'designer dogs') are dogs of mixed ancestry. They are robust and often make great pets. Keep in mind though, that when you purchase a crossbred puppy it might be difficult to accurately predict how these puppies will develop. Both purebred and crossbred puppies and adult dogs are available at RSPCA Adoption Centres.
Ideally, dogs should be taken to council-designated areas where they can be safely let off the leash to run free. It is important to use these specifically designated areas not only to ensure their own safety (preventing the risk of being hit by a car) but also the safety of farm livestock and wildlife which can be threatened by a dog let loose in their habitat.
However, if you decide to keep your dog outdoors, it is important to consider how you'll ensure it receives the appropriate amount of human contact (particularly during those cold winter months in which we'd all much rather stay snuggled inside rather than playing fetch with our pals in the cold!). An option could be to enlist the service of a dog walker. Also, if you work long hours or are sometimes forced to take overnight trips, it may be useful to consider "doggy day care" facilities to ensure that your dog receives the TLC and companionship it will need in your absence.
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.
Lungworm larvae may be present in slugs and snails, and if eaten, pets may be infected with worms that make their way to the lungs, where they block airways and make breathing difficult. Most dog wormers don't claim to treat lungworm, although some cat wormers do. Research conducted internationally has found moxidectin, which is found in some heartworm treatments for dogs, to be effective against lungworm, but this claim can't be made for dogs on packaging in Australia. Check with your vet as to whether it's an issue in your area, and discuss the best preventative treatment.
