Possible Causes of Excessive Shedding in Dogs

Shedding refers to the loss of hair in dogs naturally. Dogs shed their older, damaged and excessive coat of hair that allows the new coat of hair to grow. Every dog sheds with the sole exception of the complete hairless dog such as the American Hairless Terrier. The degree of shedding may vary from dog to dog or breed to breed.

Why does my dog shed so much?

Though shedding, even excessive shedding in dogs can be normal, in many cases it can be caused by both nutritional and environmental factors. In dogs, shedding also depends on seasonal changes.

Some people clip their double coated dogs in the hope that this will reduce shedding. However, this is not a good idea as it may damage the coat and in fact increase shedding in the future. See Should you clip a double coated dog to learn more.

1. Seasonal Shedding

Dogs have a seasonal shedding season in the spring, as their winter fur coats are gone. The shedding is at its peak in the summer season when they want to cool themselves down in the heat and in winters they gain a thicker coat of hair to keep themselves warm and insulated.

2. Hormonal Shedding

Apart from the seasonal factor, hormones play a vital role in dogs once they attain puberty, especially in female dogs. After the females have whelped or gone through their heat cycle, they often drop their coats and the cycle of shedding keeps going. Loosing hair during gestation and lactation is very common in female dogs.

3. Shedding due to poor diet

Improper diet could be one of the causes of shedding in dogs. Often dogs are given the food that they find difficult to digest, for example, food like grain bran and corns. Due to digestive problems, their skin turns dry causing the loss of their fur coat.

4. Dehydration

Dehydration or the lack of water in the body can lead to dry skin, which can cause excessive shedding in the dogs. Dehydration of the body is not just limited to the shedding in the animals, but it can also cause severe illness.

5. Fleas and Ticks

 Dogs with flea or tick problems scratch continuously, which causes hair to fall out easily. See here for natural ways to fix fleas in dogs.

  1. My 7 month old, female, piebald, long-haired mini, is shedding like crazy. It looks as if she has an undercoating that is slightly lighted in color. She has not yet gone in heat, is healthy, perky and eats well. Prior to this, she had a beautiful copper coat. We do live in Fl, and it’s hot. Wondered if that had anything to do with it. We are freaking out!

      Thanks for your comment. As this is a sudden change I would consult your vet just to eliminate any potential health issues such as a hormone imbalance. It is not unusual for a puppies coat to change color as they develop their adult coat. The change in color could also be due to sun bleaching. I hope this helps. Thanks
