What are Elevated Sex Hormones?

Androgens are produced by the testes, ovaries and adrenal glands. Although they are primarily a male hormone, they are found in females also where they are a precursor to estrogen. In dogs, excessive androgen production is associated with hair loss and oily greasy skin (seborrhea oleosa) that is usually focused around the tail and rump area. This occurs primarily in male dogs that have not been castrated where it is called hyperandrogenism. It is more common in middle-aged or older dogs, and may be either idiopathic or due to interstitial tumors on the testes. Dogs with tumors may often have ring-like growths around the anus or perineum. Dogs may also exhibit behavioral changes, such as aggression and an increased sex drive. Most conditions are responsive to castration, which is the recommended treatment. Similar disorders involving non-inflammatory hair loss can also be found in females and non-castrated males of any age. This is usually referred to as Alopecia X. This disorder isn’t fully understood, but it’s believed that an imbalance in the adrenal sex hormones disrupts the hair cycle. Alopecia X is more common in some breeds. Most cases are idiopathic although versions of the disease can occur with endocrine disorders like Cushing’s disease and hypothyroidism.

In dogs, elevated male sex hormones, called androgens, are associated with non-inflammatory hair loss, and oily or discolored patches of skin. Hyperandrogenism is a disease that occurs from elevated hormone levels in non-castrated males. If similar symptoms occur in females or dogs that are neutered, it is called Alopecia X.

Symptoms of Elevated Sex Hormones in Dogs

These abnormal symptoms should be evaluated by a veterinarian, especially if your dog is an uncastrated male.

  • Hair loss focused on the hind quarters
  • Dry or bleached hair
  • Scaly or oily skin
  • Hyperpigmentation (areas of dark colored or brown skin)
  • Masses on the testes
  • Aggressive behavior
  • Increased sex drive


Several types of elevated hormones can cause similar symptoms.

  • Hyperandrogenism – occurs in uncastrated males
  • Hyperestrogenism – elevated estrogen levels can also cause symptoms of hair loss (more common in unspayed females)
  • Alopecia X – a generic term for non-inflammatory hair loss that is probably caused by a complex hormone imbalance; a number of different names have been used to describe this disease based on treatments, including growth hormone responsive alopecia, melatonin responsive alopecia, and Lysodren responsive alopecia

Causes of Elevated Sex Hormones in Dogs

Some conditions can make elevated sex hormones more likely.

  • Lack of castration in males
  • Tumors of the testes
  • Tumors on the ovaries (more commonly causes hyperestrogenism)
  • Endocrine disease (Cushing’s disease - atypical, hypothyroidism)
  • Breeds that are more likely to develop Alopecia X (Miniature Poodle, Pomeranian, Chow Chow, Akita, Samoyed, Keeshond, Alaskan Malamute, Siberian Husky)
  • Idiopathic

Diagnosis of Elevated Sex Hormones in Dogs

The veterinarian will perform a thorough physical examination and evaluate your dog’s symptoms. If your dogs is an uncastrated male, hyperandrogenism will be suspected, especially if the sexual organs or tail gland is enlarged. In most cases blood and urine tests will come back normal. The veterinarian will check for signs of inflammation which could suggest a differential diagnosis, and may evaluate a cellular culture microscopically to check for fungal or bacterial infection. X-rays or ultrasound could be ordered to identify tumors on the testes.

The veterinarian will try to eliminate other potential causes of alopecia, especially if your dog is not a castrated male. This includes an ACTH stimulation, a specialized endocrine test to check for Cushing’s disease and thyroid imbalance. Elevated progesterone levels after testing can sometimes indicate an adrenal sex hormone imbalance. Sex serum levels will be tested also. X-rays may be needed to check for glandular tumors. Breed can be relevant for cases of Alopecia X, so the veterinarian will need to know your dog’s family history.

Treatment of Elevated Sex Hormones in Dogs

Castration is the first treatment for hyperandrogenism. Cancerous tumors on the testes will be removed at the same time. Male dogs usually have this procedure on an outpatient basis. Your dog will need to limit exercise for several days and may have a swollen scrotum. If there are stitches, you will need to return to have them cut, and the vet may want a post-operation check-up anyway. The procedure could be more extensive depending on the placement of testicular tumors.

Many symptoms are responsive to castration. If the problems returns however, or if your dog is already neutered or female there are some other treatment options. Idiopathic cases of Alopecia X are often treated with the hormone melatonin. This is effective in about 40% of cases, but it may take 3 months of treatment for your dog’s hair to regrow. Medroxyprogesterone is another hormone that can sometimes be more effective, but it also has more negative side effects than melatonin.

Conditions that are caused by a form of Cushing’s disease are often responsive to Lysodren (mitotane). This is a more drastic treatment with potential side effects, but if excess cortisol precursors are stimulating sex hormone production, it can be effective. Other options your vet might recommend for severe or stubborn cases include growth hormone administration and trilostane, another medication used to treat Cushing’s disease.

Recovery of Elevated Sex Hormones in Dogs

Many cases of hyperandrogenism are responsive to castration and your dog will make a full recovery. Some dogs may need retraining after surgery to help modify aggressive behaviors that have become habitual. 

Some cases of Alopecia X are also responsive to treatment, but the cause of this condition is less well understood and can be harder to pinpoint. The symptoms are mainly cosmetic, however, and can be managed even if hair loss persists. Frequent bathing and the use of anti-seborrheic shampoos can help to improve skin health. Antibiotic or antifungal creams will limit the chance of a secondary skin infection. This may be necessary even while your dog is taking medication as most drug treatments take a while to produce an effect. Always discuss the side effects of any treatment plan with your veterinarian.

elevated sex drive, hair shedding,

My 4 yrs old Lhasa Apso (not neutered) is excessive shedding since he is 9 month old and no Vet was able to figure out what is going on. He is losing hair on his tail (more its breaking) and on his rear flanks and legs and his rump. The front part is not shedding and his neck hair is superlong. His rump hair is thin and has no undercoat at all.In other words he looks like a lion.The hair in the front looks healthy and good colored while the rest is thin, brittle and on his paws superdry and frizzy. His belly gets black colored.
Now I just google elevated sex drive in dogs, because thats what he is doing mostly everyday, he just suddenly comes and sperm is all over my place. If that might cause his shedding than I really have to consider castration.
So how can we figure out if that is actually the problem of his shedding? He also suffers anxiety, panic attacks and sees imaginary things around him, than he gets scared and runs hiding in my closet.I was thinking his cortisol might be elevated. I am very worried about him and need to know what to do best.

DJ is normally a very relaxed, lazy dog. He likes cuddling with me, stealing my pillows from me, and whenever he doesnt feel like laying on the bed, he lays under my bed, and usually comes out when I call him. He's not a fan of going outside, usually preferring staying inside, but he'll go if I force him to or tell him to. However, last night, he had a sudden burst of "affection" I guess, crawling into my lap and whimpering. But when my other dog came to get some attention too, he growled very loudly at him. Louder than he usually does, and he really only growls at him when our other Dog, Pluto, gets too close to his food dish, in which case he'll just run to the dish and sit by it. But now, hes acting aggressively towards our other dogs, not really towards us, and he's not leaving from under our bed, and he didn't finish the treat I gave him earlier. He wont look at me or my Dad and he yipes randomly, but I cant tell why because I can't see him when he does yipe and the look he gives me when I reach under the bed and pet him isn't right. However, his fur comes out in tufts on his rear end, specifically his hind quarters, and he has been shivering a bit, and I know he isnt neutered. Could this be what's wrong with him, or is it something else?

I have 4 year old Japanese Akita. She comes to heat every four and half months. I did seven progesterone test, which were too low for breeding. Every time befor the heat she sheds and get a pimples between ears and the both sides of the tail. Her hair is brittle and undercoat is bad. She is not itching! I don’t know what to do! I did take her to vets and to dermatologist, nothing!

If a Dermatologist was unable to diagnose the problem, I cannot think of anything else that they wouldn’t have covered during their examination; some conditions may be affected by hormonal changes and Japanese Akitas are prone to some different dermatologic conditions (my only real thought may be sebaceous adenitis). If you’re unable to breed with Kuma and these episode occur during estrus you should think about spaying her. Regards Dr Callum Turner DVM

My TFT is experiencing symmetrical hair loss after being exposed to my bioidentical hormone cream I put on my arms. This has been a progressive hair loss. We just had an expensive thyroid test done and there is no issue with her thyroid. What can I do to get her hair to grow back? It is thinning on her back and she has black skin spots under the hair. Will it grow back now that she is no longer exposed to the hormone cream? Her tummy is bare as well as the backs of all four legs.

Normally the best course of action is to remove the source of the hormone from the dog’s environment; regrowth of hair should occur but it may take a while and could get worse before it gets better. Monitor Sugar Bear for now, but if there is no improvement over the next month or so you should visit your Veterinarian for an examination. Regards Dr Callum Turner DVM

Re: Dr. Turner's response, would it be helpful if I gave her a hormone balancing supplement endorsed by Dr. Mercola? My own vet recommends expensive skin and hair tests which we cannot afford. I know the problem started with my topical hormone cream exposure so she must have a hormone imbalance.

Aggression toward other females

My 9 year-old mixed breed (rescued, so not sure of breed, but probably some Corgi, maybe some Labrador) sometimes exhibits very aggressive behavior toward other dogs, particularly females. It seems to have gotten somewhat worse with age, so that she even sometimes attacks my other, younger female for no apparent reason - literally for breathing wrong while she is sleeping/dreaming! I have also noticed an increase in shedding in the last two years, so it is almost constant. She is otherwise seemingly healthy. Note that while she was in her previous home, at less than a year old, she was impregnated by a few different males, and had a litter of 12 pups before she was a year old. I took her to the vet and got her spayed after that litter was weaned and the appropriate time had passed, or so we thought, but I am concerned it may have affected what may have been an already protective and dominant nature.

I think that is would be best to hire a trainer to work with Dot, and your family, to correct this behavior before it escalates. Sometimes these behaviors are reinforced as dogs age, and if Dot is spayed, it likely isn't hormonal as much as behavioral. Hiring a good trainer who uses positive techniques will allow them to work with her and teach you how to change the behavior. If you need a trainer, your veterinarian can recommend one in your area. I hope that all goes well for her.
