At some point you’ve probably asked yourself, “Why is my dog itching so much?”

Skin problems are incredibly common in dogs, and most of them make dogs scratch, rub, or lick at their skin.  

Let’s look at the best ways to provide itch relief for dogs and the most common causes of an itchy dog.

Key Takeaways

  • Several common health problems can cause itchiness in dogs.
  • Make an appointment with your vet if home treatments aren’t effective for your dog.
  • Whenever possible, itch relief for dogs should be aimed at the underlying problem.

What Causes Itchy Skin in Dogs?

Many common health problems can make dogs itchy, including:

Home Remedies for an Itchy Dog

The first thing to do when faced with an itchy dog is to check their skin. The cause may be obvious.

Treatment for environmental allergies can involve prescription medications like Zenrelia.

If you see an attached tick, you can remove it at home.

Do you see lots of fleas? Good flea treatments like K9 Advantix II and Frontline Plus are available over the counter.

Sometimes you can’t immediately see the cause behind your dog’s itch. As long as your dog isn’t too itchy, you can try some home remedies:

Make an appointment with your veterinarian if home treatments aren’t effective for your dog.

When To Call Your Vet About an Itchy Dog

Don’t try treating an itchy dog at home if their scratching and biting are severe enough that they have patches of hair loss, very red skin, or open wounds.

These clinical signs mean a dog should be seen by a veterinarian for diagnosis and treatment.

Itchy skin in dogs is rarely a veterinary emergency (except in the case of anaphylaxis). However, if your dog is really suffering, seek veterinary care right away.

How Vets Diagnose the Cause of an Itchy Dog

Your veterinarian will start looking for the cause of your dog’s itching by doing a thorough physical examination and asking you some questions, such as:

  • Is your dog on parasite prevention? What kind and how often do you use it?

  • When did you first notice your dog’s itchy skin? Is it getting better or worse, or is it about the same?

  • Is your dog itchy all the time or just during certain seasons?

  • Have you tried any home remedies, and have they worked?

  • Are other pets or people in the home also itchy?

  • Have you noticed any other symptoms?

At this point, your vet may be able to recommend treatment, but more testing could also be needed. This can include:

Most of the time, a veterinarian will start with the simple, inexpensive tests and only move on to other testing if your dog doesn’t respond well to treatment.

Treatment for an Itchy Dog

Whenever possible, itch relief for dogs should be aimed at the underlying problem:

  • Treatment for environmental allergies can involve prescription medications like Zenrelia. A single daily dose of Zenrelia can help to quickly relieve a dog’s itch.

    • Along with medications like Zenrelia, your vet may also recommend baths, immunotherapy (allergy shots or drops), omega-3 fatty acid supplements, or antihistamines.

  • Food allergies are managed with a diet that doesn’t have the dog’s specific allergens. Veterinary diets may be needed in severe cases.

  • Fleas, ticks, mites, and lice can be removed with the right parasiticides. Your veterinarian can help you pick out the best medication for your dog.

  • Bacterial and fungal infections are often treated with medicated baths and with prescription antibiotics or antifungal medications.

How To Prevent Itchy Skin in Dogs

Keeping a dog’s skin as healthy as possible can go a long way toward keeping them itch-free. Ways you can prevent itchy skin in dogs include:

Look over your dog’s coat and skin very well at least once a month. This will help you catch any problems that do develop early—when itch relief for dogs can help the most.

Itchy Dog FAQs

What can I do to relieve my dog’s itchiness?

Closely check your dog’s skin to see if you can find any obvious problems like fleas. A soothing dog shampoo may also help, but speak to your veterinarian if the itching continues.

Why is my dog so itchy but there are no fleas?

Fleas may still be to blame for a dog’s itching even if you can’t see them. It can take just one bite to make a dog with flea bite allergies extremely itchy.

Other common causes for dog itchiness include environmental allergies, food allergies, other parasites (like mange mites), and bacterial or fungal infections.

What can I give my dog if she’s itchy?

Whenever possible, it’s best to treat the underlying cause of a dog’s itching, but sometimes symptomatic treatment is needed too.

Bathing your dog—particularly using a vet-approved calming shampoo and offering omega-3 fatty acid supplements—can reduce itching in dogs.
