The expression Hip Dysplasia can be interpreted as the abnormal or faulty development of the hip. Abnormal development of the hip causes excessive wear of the joint cartilage during weight bearing, eventually leading to the development of arthritis, often called degenerative joint disease DJD or osteoarthritis. The terms DJD, arthritis and osteoarthritis are used interchangeably. HD is a developmental disease meaning that it is not present at birth, but develops with age. Studies show a connection between excessive laxity and the development of DJD. Generally HD is considered to have a genetic base; giving the dog a predisposition to the way its hips are formed at birth and how much laxity is present in the joint.

Sarcoptic Mange (Scabies): Causes, Symptoms, & Treatments
Demodicosis , also called demodectic mange or red mange , is caused by a sensitivity to and overpopulation of Demodex spp. Demodex is a genus of mite in the family Demodicidae. The mites are specific to their hosts, and each mammal species is host to one or two unique species of Demodex mites. Therefore, demodicosis cannot be transferred cross species and has no zoonotic potential. Demodicosis in humans is usually caused by Demodex folliculorum and may have a rosacea -like appearance. An association with pityriasis folliculorum has also been described.
Notoedric Mange (Feline Scabies)
James H. Mites are among the smallest arthropods with most barely visible without magnification. Animal and plant mites establish their mite islands in animal dens, bird nests, trees, on fruits and vegetables, and even on cheeses and furniture.
Most dogs can tolerate a small number of mites. However, a mite infestation can pose serious health problems for puppies. Demodex mites live in the hair follicles of most dogs. Most dogs have a small number of mites.
