Canine Distemper is a widespread, often fatal neurological disorder that is the most feared canine disease in the world. All dogs, even older ones, should be vaccinated against canine distemper.

Canine Adenovirus types 1 & 2 cause infectious hepatitus and respiratory infection, respectively. Hepatitus caused by adenovirus type-1 may cause severe kidney damage or death. Adenovirus type-2 is an important factor in kennel cough.

Canine Bordetella {B. bronchiseptical} may contribute to the kennel cough syndrome. This bacterial infection can occur alone or in combination with distemper, adenovirus type-2 infection, parainfluenza, and other respiratory problems.

Canine Leptospirosos {lepto} is a bacterial infection which may lead to permanent kidney damage. The disease is easily spread to other pets and to humans.

Canine Parainfluenza is another cause of the kennel cough syndrome. Although parainfluenza is often a mild respiratory infection in otherwise healthy dogs, it can be severe in puppies or debilitated dogs.

Canine Parvovirus {parvo} is a widespread disease that may cause severe dehydrating diarrhea in dogs of varying ages. Parvovirus is especially dangerous in puppies.

Rabies, one of the world's most publicized and feared diseases, is almost always fatal. Rabies virus attacks the brain and central nervous system, and is transmitted to humans primarily through the bite of an infected animal.

Canine Coronavirus {corona} is a highly contagious intestinal disease causing vomiting and diarrhea in dogs of all ages. Especially in young puppies, dehydration from corona infection can be life-threatening.

Lyme, a bacterial disease caused by Borrelia Burdorferi, may be spread through direct contact and insects such as flies, fleas, and ticks. Arthritic-like symptons may occur.
