Giardia intestinalis and Giardia duodenalis are single celled protozoan parasites, which inhabit the affected dog’s small intestine, causing clinical signs of Gardiasis. The protozoa attach themselves to the intestines and multiply. They may be directly swept through the intestines and appear in the infected dog’s faeces or they may develop into a tougher more durable ‘cyst’ form, which is again passed in the dogs faeces but is able to survive for long periods in the external environment. Dogs are infected by ingesting the cysts from contaminated water and the environment. Infected dogs may not show any clinical signs of Gardiasis, but they can still shed the protozoa from their systems, spreading the infection to other healthy animals.   Infection and subsequent illness is more commonly seen in younger animals. Signs of infection include: chronic or intermittent diarrhoea that may appear ‘fatty’ and slimy, accompanied by a very foul smell. Weight loss is also possible if left untreated.

The expression 'man's best friend' is truly fitting in describing one of man's most loyal and loving four-legged companions. Owning a dog is part of the Australian way of life - providing companionship, loyalty, and bundles of love for people of all ages, dogs are an invaluable addition to the family. Nonetheless, it is important to think carefully about the responsibility of dog ownership before you adopt or purchase a dog.
While fleas are annoying, ticks can be deadly. The paralysis tick occurs mainly in spring and summer in Eastern Australia, and is found in long grass and the bush. Tick protection isn't necessary for all dogs and cats, and depending on where you live, may not be needed all year round – your vet can advise you on the situation in your local area. No tick preventative is 100% effective, so you still need to check your pet every day.
Puppy Roundworms can infect humans. To prevent this infection, puppies should be wormed regularly throughout their first year of life, and owners should be thorough with their own personal hygiene after having interacted with the dog. Tapeworms, Hookworms, and Whipworms can also infect dogs, and your veterinary surgeon can advise when to worm the dog.
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.
Fleas are a common external parasite associated with dogs. They cause severe itching and inflammation of the skin, leading to dermatitis. They are the intermediate host for the Tapeworm most common in dogs. If fleas are a problem, it is necessary to treat all animals in the household (both cats and dogs) to clean the environment. You may also want to ‘flea bomb’ the house to remove any eggs and to stop the cycle. Preventative programs are best achieved using “spot on” products that have a prolonged residual effect, usually 30 days. However it is strongly advised to consult your Vet or chat with the RSPCA's friendly Vet nurse team for free advice about the most suitable product for your pet.
It is important to buy your dog from a reputable source. Purchase your dog from a reputable dog breeder, visit an RSPCA Adoption Centre or a local animal welfare shelter such as the RSPCA where lots of happy and healthy dogs are looking for loving new homes. If you are looking to adopt a dog from a breeder, make sure you read our Smart Puppy Buyers Guide.
