Constant scratching, licking, or chewing usually means your dog or cat is itchy, and allergies are one of the most common causes. Triggers include fleas, environmental allergens like pollen and dust, and certain foods. At Cypress St. Animal Hospital in Kitsilano, your veterinarian can find the cause and bring your pet relief.
What itchy skin actually looks like
Itching is not always obvious scratching. Pets show discomfort in many ways, including licking or chewing the paws, rubbing the face on carpet, scooting, recurring ear infections, hair loss, red or flaky skin, and a coat that smells different than usual. Some pets groom so quietly that owners only notice bald patches or sores after the fact. Recognizing these signs early is the first step to helping your pet feel comfortable again.
Common causes of itching
Several things can make a pet itchy, and sometimes more than one is at play. Fleas are a frequent culprit, and some pets are so sensitive that a single bite triggers intense itching. Environmental allergies, often called atopy, are reactions to things like pollen, grasses, dust mites, and mould, much like hay fever in people. Food sensitivities can also cause itchy skin and ears, and mites or skin infections may develop on top of any of these.
Because the causes overlap and look similar, guessing at home rarely solves the problem. What looks like a simple dry patch can be an allergy with a secondary infection that needs proper treatment to settle.
The summer connection in Vancouver
On the West Coast, itchy season often ramps up in the warmer months. Pollens rise in spring and summer, fleas multiply in the heat, and more time outdoors at Kitsilano Beach or on West Side trails means more contact with grasses and allergens. If your pet seems itchier at a certain time of year, that pattern is useful information for your veterinary team.
Why you should not just wait it out
Itching is genuinely uncomfortable, and pets who scratch and lick constantly can break the skin, leading to painful infections that are harder to treat than the original problem. Persistent itch also affects sleep and quality of life. Addressing it early, through our medical services, usually means simpler, faster relief and a more comfortable pet.
How your veterinarian finds the cause
Finding the trigger is part detective work. Your veterinarian starts with a thorough exam of the skin, coat, and ears, and asks about diet, parasite prevention, and when the itching occurs. From there, pet diagnostics such as skin samples to check for infection or mites, and in some cases allergy testing or a carefully managed food trial, help pinpoint the cause. A food trial guided by our nutrition counselling is often the clearest way to rule a food sensitivity in or out.
Relief and long-term control
Treatment depends on the cause and often combines a few approaches: reliable year-round flea prevention, treating any skin or ear infection, and calming the itch itself with options your veterinarian recommends. Many allergies cannot be cured but can be managed very well, so your pet is comfortable through the seasons. Regular check-ins through our wellness program help keep the plan working as triggers change across the year.
At home, you can help by keeping flea prevention consistent, noting when flare-ups happen, avoiding frequent harsh shampoos unless your veterinarian advises them, and wiping paws after walks during pollen season. Small, steady habits make a real difference.
When itching needs prompt attention
Most itching can be sorted out at a regular appointment, but some situations deserve quicker care. A rapidly worsening hot spot, a raw or oozing sore that appears overnight, intense head shaking with a painful ear, or sudden facial swelling and hives can all escalate quickly and cause real discomfort. Pets who cannot stop scratching may injure themselves within hours, so it is worth calling sooner rather than waiting it out.
It also helps to keep a simple record between visits. Note when the itching is worst, which areas your pet targets, what you have changed in food or environment, and whether any new product was used. These details often reveal a pattern that points your veterinarian toward the cause, and they make each appointment more productive for you and your pet.
Frequently asked questions
Is it normal for my pet to scratch sometimes?
Occasional scratching is normal. It becomes a concern when it is frequent, focused on one area, or paired with redness, hair loss, odour, or skin changes. If it is interfering with rest or daily life, have it checked.
Could my pet have a food allergy?
It is possible, though environmental allergies and fleas are more common. A carefully managed diet trial guided by your veterinarian is the most reliable way to know, since over-the-counter tests are not dependable for food.
Why does my pet keep getting ear infections?
Recurrent ear infections are often a sign of an underlying allergy rather than a standalone problem. Treating the infection helps, but identifying and managing the allergy is what prevents them from returning.
Can I just bathe my pet to fix the itch?
Bathing can soothe skin, but the wrong frequency or product can make things worse, and it will not address an underlying allergy or infection. Ask your veterinary team which approach suits your pet.
Will my pet need allergy treatment forever?
Some pets need only seasonal support, while others with year-round allergies benefit from ongoing management. The goal is steady comfort, and your veterinarian will tailor the plan to your pet.
