If your dog is constantly scratching, licking their paws, rubbing their ears, or chewing at their skin, it’s easy to assume it’s something minor.
But here’s the reality: chronic itching in dogs is not normal — and it almost always means there’s an underlying problem.
At McQueen Animal Hospital in Brampton, itching is one of the most common issues we see — and in many cases, it’s something that keeps coming back if not properly diagnosed.
What Causes Itching in Dogs?
Itching (also called pruritus) is not a disease — it’s a symptom. The key is identifying why it’s happening.
- Allergies (Most Common Cause)
This is by far the most common reason dogs itch. Allergies can be environmental (pollen, dust, grass, mites) or food-related (chicken, beef, dairy, etc.). Dogs with allergies often show paw licking, ear infections, and red skin. Many also suffer from recurrent ear infections.
- Fleas (Even If You Don’t See Them)
A single flea bite can trigger intense itching, and some dogs are allergic to flea saliva. You may never actually see the flea.
- Skin Infections (Bacterial or Yeast)
These are often secondary problems, especially in allergic dogs. Signs include red, inflamed skin, greasy or smelly coat, dark discoloration, and worsening itch over time.
- Ear Infections
Ear infections are strongly connected to itching. Dogs may scratch their ears, shake their head, and develop discharge or odor. If your dog has both itchy skin and ear infections, allergies are very likely involved.
- Parasites (Mites, Mange)
More common in puppies or immunocompromised dogs, parasites can cause intense itching and skin damage.
Signs You Should NOT Ignore
- Constant scratching or biting
- Licking paws excessively
- Red or inflamed skin
- Hair loss or thinning coat
- Bad odor from skin or ears
- Recurrent ear infections
These are not temporary problems — they usually indicate a chronic condition.
Why Does the Itching Keep Coming Back?
Common reasons include underlying allergies not diagnosed, short-term or incomplete treatment, repeated yeast or bacterial infections, and lack of a long-term management plan. Treating symptoms alone is not enough — the root cause must be identified and controlled.
How We Diagnose Itching at McQueen Animal Hospital
- Detailed skin and ear examination
- Cytology (microscopic evaluation of samples)
- Identification of yeast, bacteria, or parasites
- Allergy assessment
- Individualized treatment plan
This approach allows us to treat the condition effectively — not just temporarily suppress it.
Treatment Options
- Medicated shampoos
- Ear medications
- Antibiotics (for bacterial infections)
- Antifungal treatments (for yeast)
- Anti-itch medications
- Allergy management (diet trials, medications)
Many dogs require a long-term strategy, especially those with allergies.
Can It Be Prevented?
- Regular grooming and skin checks
- Keep ears clean and dry
- Consistent flea prevention
- Treat early before it worsens
- Regular veterinary exams
Early intervention means easier treatment and less discomfort.
