Why does my dog ​​lose hair and what should I do about it?

Most of us dog owners at some point had to worry about hair loss. Hair loss may be normal or may be from itching and scratching (self-inflicted hair loss, such as sarcoptics, fleas and allergies), and sometimes hair may fall out in small spots (such as ringworm) or in large areas (eg hypothyroidism). ).

None of these problems is an emergency. Your dog may be uncomfortable, so you need to take care of things as soon as possible, but you don’t have to worry about finding a clinic in the middle of the night.

If your dog is losing hair, take a deep breath and try to understand what is happening. Do not rush to conclusions – read all the conditions to see what can fit. Check out the photos and videos here, do more research on other websites, and if you need help, take your dog to your regular vet as soon as possible.


Normal causes of hair loss in dogs

  • Normal flooding (seasonal or year-round)
  • Poor condition (hunger)
  • Parasites (such as fleas, mange, ringworm, yeast, etc.)
  • Allergies (can be inhalation, food or even contact allergies)
  • Infection (hot spots, folliculitis, cellulite and some others)
  • Hormonal problems (hypothyroidism, pillows, excess or deficiency of estrogen)
  • Autoimmune diseases (secondary to skin ulcers)
  • Other uncommon diseases (such as acanthosis nigra, fatty adenitis, zinc dermatosis, blue Doberman syndrome, dysplasia of black hair follicles, etc.)

What causes your dog’s itching?

Sometimes a dog that loses hair just sheds. The dog will not have bald spots. If it itches and scratches, it will help you decide what condition causes hair loss.

If your dog itches, it may be:

  1. Fleas : Even if you don’t see any fleas, this is a problem if you see “flea dirt,” black patches of dried blood that you sometimes find on a dog. Take a few of the stains and place them on a wet paper towel – if the paper towel turns red around the spots, your dog will have fleas. Most readers know how to get rid of fleas, be it with monthly spot products or natural methods . Unfortunately, fleas become resistant to spots and natural methods do not always work. Some dogs still have hair loss and excessive itching from fleas, especially on the back just above the tail.
  2. Allergies : The first thing many people think of after fleas are allergies. They can be caused by something in the air, something in the food, or even a meal with food or a favorite blanket. Allergic dogs can have inflamed skin, red ear canals, swollen lips and red eyes, and even a runny nose. If your dog has many of these signs and is scratched a lot, allergies are possible.
  3. Mange : There are two types of man; The sarcoptic is easy to treat, demodectic mange is sometimes a mild infection, but if it becomes generalized it will require a lot of medication and a lot of visits to your vet. Both may itch, but the sarcoptic type will drive a dog insanely almost insane, and the demodectic edge may itch a little, but it can become generalized and lead to other serious health problems; if you notice hair loss and itching the best thing you can do is take it for a veterinary checkup and scrape the skin.
  4. Ringworm, yeast or bacterial infection : You may not even notice itching with these problems, but the skin will thicken, flake off, and the hair will fall out in an uneven pattern. Sometimes itching is a sign of a secondary infection.

Infections that cause itching in your dog

  • Hot spots are a local infection that usually begins under patches of thick hair. If you know what they look like and want to take care of the infection at home, you can cut your hair, clean your skin with betadine from your first aid kit, and then apply a topical antibiotic cream from your pharmacy. Your veterinarian may also put your dog on oral antibiotics and may give him a steroid shot so he doesn’t scratch it on the spot and make the infection worse.
  • Folliculitis is an infection of the hair follicles. Some dogs (such as miniature schnauzers) can get this infection on their own, but many times it is secondary to other infections such as men. The dog can be treated at home with Pyoben shampoos twice a day, but your veterinarian may need to give him oral antibiotics.
  • Cellulite is an infection of the skin and tissues just below. As with folliculitis, there is not always hair loss, but because it is painful your dog can rub it and the hair will come off. Treat it by soaking in Epsom salts (about 30 grams or ¼ cup to 1 liter of water, about 3 times a day) and keep the skin over the infection clean with betadine. If this is not enough, your veterinarian may want to treat your dog with antibiotics.

Use a good shampoo to improve infections

All skin infections can be improved by using a good shampoo, so if your dog is itchy and you can’t figure out what’s wrong, I’ve found that this brand helps. To use it properly, wet your dog thoroughly, apply the shampoo and leave it for at least 10 minutes. This is a long time, so be sure to check your watch so that it is not released too soon. If your dog does not like to be in the bath for so long, you can massage it after shampooing and distraction will make many dogs forget the time.

What to say when my dog ​​loses hair without itching?

If your dog does not itch, but does not just shed normally, the cause of hair loss can be:

  1. Hypothyroidism : Because the thyroid gland controls your dog’s metabolism, the first thing some people notice is gradual weight gain. The hair is dry, brittle and falls out easily in an even pattern (it is the same on the left as well as on the right). As there can be many other symptoms, including aggression, the dog must see his veterinarian and have a blood sample taken so that the disease can be diagnosed and treated.
  2. Hyperadrenocorticism (Cushings): This disease is caused by an excess of steroids in the body and has many clinical symptoms, but changes in the skin are sometimes most obvious. The skin becomes dark, dogs lose hair everywhere, dogs may have blackheads on the abdomen, and the abdomen is large and swollen on top. Some owners will notice that dogs are really thirsty and therefore need to go out more often. These problems can sometimes be treated successfully, so like hypothyroidism, the dog must be seen and diagnosed by a veterinarian to begin treatment.
  3. Other hormonal diseases (estrogen excess, estrogen deficiency, alopecia corresponding to growth hormone) If your dog has a tumor that causes extra estrogen, his skin and coat will begin to darken around the abdomen and then the hair will become brittle and fall out. . She will need testing to determine if this is the problem, but can it be treated by spraying or castrating. If there is not enough estrogen, the hair falls on the abdomen. Hormonal diseases can only be diagnosed after blood tests, so you should take her to your veterinarian.
  4. Autoimmune diseases : Hair loss caused by these diseases is insignificant compared to skin ulcers and secondary infections. If your dog has skin ulcers, hair loss is the least of his problems; the only way to diagnose this is to send a skin biopsy to a lab.

If your dog has Tibetan Mastiff-like symptoms seen in this video, go ahead and take him for an exam and a blood test. There is no cure for this hormonal disease, but drugs to treat hypothyroidism are cheap and will make her look better and act like herself.

Uncommon diseases that cause hair loss

  • Fatty adenitis is an inherited skin disease. Dogs with long hair (such as the Akita, Samoyed and Standard Pudle) have hair loss on the neck, tail and top of the head. In short-haired breeds (such as Viszla) there is hair loss on the ears, legs and head. All breeds have scaly, oily skin and should be diagnosed by skin biopsy and then treated by a veterinarian.
  • Zinc-responsive dermatosis can occur in some dogs fed cheap food, but sometimes breeds such as Siberian Huskies, Alaskan Malamutes and Doberman Pinschers develop this even when they eat enough zinc. Dogs have hair loss around their ears, eyes and mouth, but they also have crisp elbows and feet. They need zinc supplements to improve, and if it is genetic, the supplements should be given for the rest of the dog’s life.
  • Acanthosis nigrans is a thick, black skin with hair loss that is found in young dachshunds. The armpits, ears and folds are greasy and black. There is no cure, but your veterinarian may be able to make your dog a little better by treating him with shampoo, vitamin E, antibiotics and melatonin.
  • Color diseases such as blue Doberman syndrome and dysplasia of follicular dysplasia of black hair. Blue disease is also seen in blue newfits, chows, whippets, Italian greyhounds and other blue dogs. The hair looks healthy, but then becomes infected. Dogs suffering from black hair disease never develop hair in black areas. There is no cure for any disease.
  • Although there are several even more unusual causes of hair loss, such as Alopecia X and Pattern Alopecia , one of the causes of hair loss that can be dealt with is Traction Alopecia . This problem affects small dogs with their hair tied in rubber bands and berets, and when they are too tight and left for too long, they make the dog bald on the top of the head. The only way to cure it is by removing the bald spot – the best way to prevent it is to give your dog a haircut that does not require a rubber band!

What can I do at home?

If you can’t take your dog to the vet for some reason, the first thing to do is check for fleas. If he has no problem with fleas and his symptoms correspond to some of the other diseases I have described above, there are some other things you can try.

  • If the problem is seasonal and you think it may be an allergy to inhalers, try some natural remedies such as raw honey.
  • If your ears and GI tract are involved and you think this may be food-related, try a hypoallergenic diet (a new protein the dog has never been exposed to before). A raw diet with whole natural proteins is best.
  • If the problem seems to be mainly in the legs and abdomen, it may be a contact allergy and you can try changing the mat.
  • If the problem is hair loss around the nose and lips, get rid of the plastic food container and replace it with a ceramic or stainless steel plate.
  • No matter what the cause of the itching, you can provide some relief by bathing your dog in oatmeal shampoo, and many holistic veterinarians find it helpful to rinse your dog with apple cider vinegar after bathing
