The Dog Itches And Falls Hair

If a dog has wool and itchy skin of the whole body, this means that it has not just a harmless moult, but a more serious affliction that should not be overlooked in any way.


The most common factor causing an animal to moult and severe itching is allergy. As you know, dogs often suffer from allergic reactions, and cause them not only improper food or poor-quality food, but also:

  • drugs that your pet has been taking recently;
  • human shampoos, not intended for washing wool;
  • synthetic materials used for making cheap overalls;
  • cleaning products for washing carpets, floors and other surfaces with which the dog may come in contact;
  • fleas;
  • house dust in badly cleaned rooms;
  • pollen of flowering plants and trees.

So, if your dog gets wool in clumps, it itches badly, sometimes even to the blood and often licks, most likely, the cause of all this is an allergy. To diagnose it in a clinical setting you need to do an allergotest.

A word of advice: remember if you added any new foods to your pet’s diet shortly before it began to itch. If the allergy was caused by food, then simply remove it from the menu.
