Dog Heartworm

Dog Heartworm (Dirofilaria immitis) can be a life-threatening disease for canines. The disease is caused by a roundworm. Dogs and sometimes other animals such as cats, foxes and raccoons are infected with the worm through the bite of a mosquito carrying the larvae of the worm. The disease in dogs and cats cannot be eliminated but it can be controlled or prevented with pills and/or injections.
