Canine Follicular Dysplasia

Follicular dysplasia is a genetic disease of dogs causing alopecia, or hair loss. It is caused by hair follicles that are misfunctioning due to structural abnormality. There are several types, some affecting only certain breeds. Diagnosis is achieved through a biopsy, and treatment is rarely successful. Certain breeds such as the Mexican Hairless Dog and Chinese Crested Dog are bred specifically for alopecia.

Structural follicular dysplasia:
Structural follicular dysplasia varies by breed but all involve weakened hairs that break easily. Hair loss is originally seen in areas of repeated grooming or trauma, for instance the neck because of contact with a collar. Hair regrowth may occur, but the hair will be even weaker and the pattern will repeat. The dogs are affected between the ages of two to four years, and it is most commonly seen on the back towards the tail. Progression of the hair loss to cover the trunk can occur.

Cyclic follicular dysplasia or seasonal alopecia:
It causes bilateral hair loss and hyperpigmentation of the flanks. The disease usually starts in the late fall or early spring, and can regrow in about six months, although the hair may be different in color or texture. Treatment with melatonin may result in hair regrowth sooner, so it is thought that the amount of daylight influences this condition. The dogs are affected between the ages of two to four years

Commonly affected breeds
• Affenpinscher
• Airedale Terrier
• Boxer
• Bulldog
• Silver Labrador
• Staffordshire Terrier
• Wirehaired Pointing Griffon

Color dilution alopecia:
Color dilution alopecia is an inherited type of follicular dysplasia. It most commonly affects dogs with blue or fawn coats, which are dilutions of black and brown, respectively. Dilution is caused by irregularities in melanin transfer and storage. Melanosomes may clump within melanocytes of the skin and hair follicles, causing the hair shafts to easily fracture. Signs of color dilution alopecia include hair loss and recurrent skin infection on the back. It can involve the whole body. The condition starts between the ages of six months and two years, depending on the degree of dilution. Early hair loss occurs due to hair breakage, making it similar to structural follicular alopecia. It is important to treat the skin infections, and etretinate has been used to treat the hair loss.

Commonly affected breeds:
• Bernese Mountain Dog
• Boston Terrier
• Bulldog
• Chihuahua
• Chow Chow
• Dachshund
• Dobermann - has the highest frequency of this condition. It occurs in 93 percent of blues and 75 percent of fawns.[1]
• German Shepherd Dog
• Great Dane
• Italian Greyhound
• Miniature Pinscher
• Newfoundland
• Saluki
• Schipperke
• Shetland Sheepdog
• Silky Terrier
• Silver Labrador
• Standard Poodle
• Whippet
• Yorkshire Terrier
