Pet Hair Loss 101: What Is Alopecia X?


If you dog has hair loss, he or she might have Alopecia X.


Alopecia X is a breed-specific hormone hair-loss disorder most commonly affecting Nordic breeds, like Siberian Huskies and Alaskan Malamutes, Chow Chows, Samoyeds, and Toy or Miniature Poodles. It’s caused by an imbalance of the sex hormones estrogen and testosterone which are produced by the adrenal glands.

Dogs with the disorder can appear completely bald, either in patches or all over their body. Other names for Alopecia X include Adult Onset Growth Hormone Deficiency, Growth Hormone-Responsive Alopecia, Castration-Responsive Alopecia, and Adrenal Hyperplasia-Like Syndrome. In Malamutes, it’s often termed Coat Funk of Malamutes and in Pomeranians, Black Skin Disease of Pomeranians.



Regardless of whether or not the pet is fixed or male or female, they can show clinical signs of the disease. Early onset symptoms appear around one year old but in some cases, hair loss doesn’t occur until as old as 10 years in some affected dogs.

Initial stages of gradual hair loss typically occurs along the trunk and back legs. The hair may fall out completely or leave a fluff before turning to complete baldness. Oftentimes the pigment of any revealed skin turns darker, even black–hence the alternate term “Black Skin Disease.”


No other symptoms are associated with Alopecia X other than hair loss and pigmentation changes. Therefore, if your dog is showcasing signs of baldness in addition to changes to normal behavior–like inappetence or excess urination–another underlying disease including Cushing’s Disease and hypothyroidism may be the culprit. To determine the root cause of gradual loss of hair, it is important to schedule a visit with your pet’s veterinarian.

While spayed, neutered, and intact canines can all have the disease, sometimes intact animals can revert back to normal hair growth once fixed due to the hormonal changes associated with spaying and neutering. Sometimes hair regrowth is only temporary, though.

Alopecia X is considered only a cosmetic condition, so treatment isn’t critical. Focusing on the hair follicle health through medicated shampooing and hormone control can be beneficial as a treatment option. Melatonin is one naturally-occurring hormone that can be given in supplement form to normalize a dog’s coat. Managing the adrenal glands, a hormone center within the body, can also help regulate fur growth.

Research is ongoing with veterinary dermatologists to determine more effective treatments for Alopecia X.

“I’m Not Leaving You, Mama!” This is What Love Looks Like.

UPDATE: Lizzie and Phantom are currently recovering in an outdoor koala ward within the  Australia Zoo Wildlife Hospital . They’re doing swimmingly; Phantom is both gaining weight and exploring his temporary habitat. And of course, mama and baby are sharing more adorable cuddles! For most species in the animal kingdom, the bond between mother and baby is incredibly strong. That's pretty much inarguable. But last week, two koalas in Australia further proved it. After they were hit by a car, Lizzie and her joey, Phantom were welcomed into the Australia Zoo Wildlife Hospital. Six-month-old Phantom had escaped the accident unscathed. Lizzie, however, wasn’t looking so good, what with facial trauma and a collapsed lung. In order to survive, she needed to go under the surgeon’s knife. But this marsupial mama wasn’t alone during the life-saving procedure. Phantom accompanied her and clung to her as she received treatment. The vets let them be; Phantom was too y...

Stop holding the (2018) Yulin dog meat & lychee festival in Yulin, (Guangxi) China.

This "festival" is an event that starts on June 21st of every year during the summer solstice and it lasts for 10 long horrifying days in which 10,000–15,000 dogs (as well as cats) are tortured and then consumed. However, it is estimated 25 million dogs are stolen, sold, bought, and eaten every year with the illegal dog and cat meat trade. A larger percentage of these dogs consist of pets stolen right from their loving families. The rest of the dogs are captured strays from the streets and some raised in dog farms. After these animals are stolen, bought, or captured they are then transported for days without any food or water, crammed in tiny cages together so tightly that they are unable to even move. At the yulin festival, throughout those days, these animals will be hung, burned, skinned, boiled, torched, dismembered, electrocuted and beaten...ALIVE..out in the streets for public view. But If that isn't bad enough, they intentionally torture these animals in f...

Dead Sea Turtle Washes Ashore With Horrifying Wake-Up Call For All Humans

Smokey the Bear told us we were responsible for preventing forest fires. Crime dog McGruff helped us take a bite out of crime. Woodsy the Owl told us to “Give a hoot, don’t pollute.” It’s that last one humans seem to have a big problem with. Where a wizened old owl’s advice has fallen short, however, the tragic image of a dead Kemps Ridley sea turtle with a beach chair stuck to its back may prove more compelling. An eye-opening illustration of the damage human pollution has done to our oceans, images of this tangled turtle have been sweeping across the internet, first posted by  Fort Morgan Share the Beach , a local chapter of the Alabama sea turtle protection nonprofit Share the Beach. The story these pictures tell is a dark one which, wildlife advocate or not, is hard to ignore.
