5 Causes of Canine Hair Loss

whippet blog 2Alopecia, or hair loss, is not just a human problem. If you’ve noticed bald spots developing on your dog, the following five culprits could be to blame:

1. Allergies: The number one cause of hair loss in dogs is allergies. Sometimes allergies are triggered by the environment (mold, pollen, etc.), other times allergies can be attributed parasites like fleas or mites. An allergic reaction typically triggers itchy skin, which results in scratching, biting, and hair loss.

2. Ringworm or other bacterial/fungal infections: Ringworm, which is actually a type of fungus, typically causes skin inflammation, irritation,  infection, and hair loss.

3. Parasite infestation: Fleas, ticks, and mites can all cause a dog’s skin to become itchy and inflamed, often leading to hair loss. Protect your dog with a parasite prevention product.

4. Cushing’s Disease: Cushing’s disease, or hyperadrenocorticism, occurs when the body produces too much of the hormone cortisol. Symptoms of Cushing’s disease include hair loss, skin darkening, and a pot-bellied abdomen.

5. Genetics: Some dog breeds, like the Chihuahua, Doberman Pinscher, Whippet, and Dachshund, are simply more susceptible to pattern baldness. The most common spots for baldness include the outer ears, back, thighs, chest, and neck.

    Not all hair loss is from a medical condition. Some breeds, like some of the herding breeds, “blow their coat” and get a new one. We have an Aussie whose outer coat dropped. Even the vet ran tests to see if it was thyroid, allergies, etc.
    Now that she is two, we see the pattern. I have since talked to owners of Border Collies who have had the same experience. The Aussie we had before did not seem to lose his hair so dramatically and we could see that it was “shedding the winter coat”. This female’s hair loss was different – rather sudden -but still just normal. She has a beautiful coat afterward. Just thought that others might have a similar experience and you might include the normal hair loss in your discussion. BTW, enjoy your articles!
