Pruritus in dogs is simply the feeling of itchiness that makes a dog want to scratch, chew, lick, or rub their hair and skin. It’s common in skin disorders, parasitic infections, skin allergies, tick and flea infestations, and several other conditions.

Even scratching at an itch, itself, can add to inflammation and pruritus in dogs. Itching can be mild and have little effect on dogs’ health, or it can be severe. Further scratching and chewing can lead to hair loss, injuries, and pain.

If your dog is showing signs of pruritus and constantly trying to relieve itches, consult your veterinarian so they can find the cause and prescribe treatment.

Here’s what you should know about the symptoms, causes, and treatments for pruritus in dogs.

  • Scratching
  • Licking
  • Chewing or biting
  • Rubbing against surfaces
  • Rolling on the ground or floor
  • Injury at the site of the itch
  • Inflammation, swelling, or redness
  • Skin infection
  • Signs of pain or discomfort (vocalization, wincing, protecting certain areas of the body, etc.)
  • Alopecia (hair loss)

Treatment for pruritus in dogs depends on the cause, but the main goals are to reduce itching and remove the source of irritation from the skin.

Some dogs are put in an Elizabethan collar to prevent them from chewing or scratching at the site of itchiness until the area heals.

Antihistamines can often treat seasonal allergies and some forms of contact dermatitis. Dry skin may be treated with fatty acid supplements. If the cause of the itchiness is a food allergy, a vet may prescribe changes in diet.

Flea infestations can be resolved with medications and special shampoos, along with preventative medication administered monthly or at various times throughout the year.

Many dog owners opt for natural flea treatments to avoid side effects of such medications. Tick infestations may also be prevented with medication or by natural means.

Vets usually treat bacterial infections are with antibiotics, and they may treat immune disorders may with immunosuppressant drugs and other forms of therapy.

If you see the symptoms in your dog, then your vet will be able to advise you on the proper treatment to relieve the itchiness.
