Why do dogs Itch?

Updated on April 3, 2016

Itchy Dog

I have three Scottish terriers, and we have been having a terrible time lately with them itching and scratching. We have learned through a lot of trial and error, some of the reasons and causes for the problem. You have to look at the area that the dog is really scratching, different areas mean different things, or they can. A sudden, intense bout of scratching, especially for a prolonged period of time or during nighttime hours when sleeping should naturally take precedence. This may manifest as itching, biting, licking, and/or chewing of one or more parts of the body, you first need to figure out which part of the body is the focus, for most dogs this type of behavior is usual something called pruritus. There are many causes of pruritus, including fleas, scabies, lice, allergies, bacterial infections, abnormal cell development (neoplasia), and immune disorders.

Rectal itching in dogs is a relatively common problem. Tis can be caused for several reasons:

One of the most common is allergies

Inflammation or infection in anal Glands- Dogs, cats, and skunks have two structures in their anus called anal glands. And what they are, are scent glands. Located at 4:00 o’clock and 8:00 o’clock within the muscles of the anal sphincter, what is supposed to normally happen is that when the dog poops, as their feces pass through the anus it squishes theses glands which then empty their, pungent, musky-smelling, contents on to the dog’s poop. When they don't work as they should they may become infected.

worms may also cause your dog to lick and scratch the anal area- Pinworms are small, white worms that spread through contaminated water, food and bedding. Common and highly contagious, pinworms cause intense anal itching. Dogs with pinworms often scooch, dragging their rear end across the floor in an effort to relieve the itch.

There are some other remedies you can try at home:

For itchy skin- medicated or oatmeal shampoos can help as well as lidocaine and cortisone sprays that you can find at your local pet store, they seem to work for our dogs.


The most important thing to remember is if the problem persist you may need to see your vet.

What causes Itchy ears?

The first thing that alerts dog owners that their dog may have an ear infection are the itchy, smelly dog ears. If the itch or smell is what tipped you off, you probably noticed a stale, ripe smell which is quite unpleasant. Sometimes the ears are just dirty and like people some dogs just produce more wax in their ears so they need to be cleaned more often. There are some great products to help clean the dogs ears on a regular basis.

The main things that cause dogs to itch there ears:

  • Ear Mites
  • Yeast

  • Bacteria

  • Fungus

    Remember check there ears completely, there could be any number of reasons they are scratching. Be careful when you check them if there is an infection they could be very painful.
