Filed Under: Dogs, Cats, Parasites

Is your cat or dog constantly scratching at its ears or shaking its head? Do the ears contain a dark brown to black crusty discharge that resembles coffee grounds, yet has a waxy consistency? Does your pet have a hot spot below one of its ears? Then your cat or dog could be suffering from an infestation secondary to an infectious mite called Otodectes cynotis, more commonly referred to as ear mites.

Do you have a rabbit that is constantly scratching at her ears? Do the ears look red and irritated? Are there big flakes of crusted material on the inside of your rabbit’s ears?

Bailey

Filed Under: Dogs, Practice Stories

Bailey, a three year-old Shih tzu, was ordinarily a bundle of energy. This day, however, he was far from acting himself. We could only get a half-hearted wagging of the tail from him, and that took some coxing. We could tell simply from the expression on his face that he was not feeling at all well.

Cheyletiellosis or Walking Dandruff in the Cat

Filed Under: Cats

Is your cat constantly scratching? Does he have scabby areas of hair loss? Does he have dandruff that you think may be moving? Then your cat could be suffering from cheyletiellosis.

Cheyletiellosis is a dermatologic condition caused by a mite so large that it is sometimes visible to the naked eye. The mite infecting cats is called Cheyletiella blakei. Although primarily a parasite of cats, cross-infections with dogs, rabbits, and foxes may occur.

Filed Under: Dogs, Parasites

Is your dog scratching, does he have bad dandruff, is he rubbing his eyes or sneezing? Does that dandruff appear to be moving? Then Cheyletiella yasquri, a large mite that parasitizes dogs, could be the source of your problem.

The Cheyletiella yasquri mite is so large that it may appear visible to the naked eye. Although primarily a parasite of dogs, Cheyletiella species are not host-specific and cross-infections with cats, rabbits, and foxes are not uncommon.

Histiocytomas

Filed Under: Dogs, Diseases

Histiocytomas are benign, fast-growing, raised, hairless skin tumors found on the extremities, head, ears, and neck. Histiocytomas account for 3 to 14% of skin tumors occurring in the dog. Typically these lesions are round and less than three cm in diameter. These tumors occur most commonly in young dogs. Boxers, Dachshunds, Cocker spaniels, Great Danes, Shetland sheepdogs and Bull terriers are especially susceptible to histiocytomas. Often these tumors will resolve spontaneously within three months and may be multiple.

Canine Tapeworms

Filed Under: Dogs, Parasites

Two types of tapeworm affect dogs, Dipylidium caninum and Taenia species. Dipylidium caninum is the more common type of tapeworm found in dogs and cats. Adult tapeworms are found in the small intestine of their host. These worms shed small segments, called proglottids (packets of 20 to 40 eggs) in the stool. Once in the environment, proglottids of the Dipylidium tapeworm are consumed by flea larvae. As the flea larva matures, the egg of the tapeworm eventually develops into its infective form called a cysticercoid. The dog or cat ingests the flea while grooming itself.

Hot Spots (Acute Moist Dermatitis)

Filed Under: Dogs, Cats, Parasites

Have you ever had an itch that was driving you insane? You just could not leave it alone even though the skin was becoming irritated? You may even scratch at the area so bad that you caused it to bleed. Everyone was trying to advise you not to scratch and yet you somehow just could not leave it alone. Sounds like a pet with a hot spot, or “acute moist dermatitis.”

Dealing With Your Dog's Allergies

Canine atopy is essentially another name for canine allergies. Most dogs with atopic dermatitis are triggered by environmental allergens, although some allergic reactions can be attributed to food allergies. The allergens causing your dog’s problems, as well as his reactions, are usually quite diverse.
