- Regular grooming with hypoallergenic shampoos and dietary changes can significantly reduce symptoms
Have you noticed your Shih Tzu scratching more than usual or developing patches of irritated skin? Many owners worry when they see their dog constantly chewing at their paws or developing dry, flaky skin. These behaviours often signal allergies, a common health challenge that affects many dogs in this breed.
When it comes to allergies in Shih Tzus, their beautiful long coat can actually work against them. That flowing double coat tends to trap pollen, dust, and other environmental allergens close to the skin, creating perfect conditions for allergic reactions to develop.
Recognising the warning signs
The most obvious symptom you'll notice is intense scratching and chewing, particularly focused on the paws, face, or belly area. Your dog might wake you up at night with persistent scratching, or you might find them obsessively licking their feet after walks.
Skin changes often follow the scratching. Look for dry skin, dandruff, or small red patches that might develop into hot spots. Some dogs experience hair loss in areas they scratch frequently. The skin around their eyes, ears, and between their toes tends to show irritation first.
Food allergies present differently, typically causing gastrointestinal symptoms like vomiting, diarrhea, or excessive gas. These symptoms might appear within hours of eating or develop gradually over time as sensitivity builds.
Understanding different types of allergies
Environmental allergies are the most common culprit for these dogs. Pollen from trees, grasses, and weeds can trigger seasonal flare-ups, while dust mites and mould create year-round problems. You might notice symptoms worsen during spring and autumn when pollen counts peak.
Skin allergies often overlap with environmental triggers but can also result from contact with certain fabrics, cleaning products, or grooming supplies. The long coat that makes Shih Tzus so distinctive also means allergens stay in contact with their skin longer than they would on short-haired breeds.
Food allergies, while less common, can develop at any age. Proteins like chicken, beef, or dairy are typical triggers, though any ingredient can potentially cause a reaction. These allergies often develop gradually, making them harder to identify initially.
Medical treatment options
For mild reactions, antihistamines can provide relief from itching and discomfort. Your veterinarian might recommend specific dosages based on your dog's weight and symptoms. These work best when started early, before scratching becomes a compulsive habit.
More severe reactions often require steroids to control inflammation and provide relief. While effective, these medications need careful monitoring due to potential side effects with long-term use. Your vet will typically prescribe the lowest effective dose for the shortest necessary period.
Cytopoint injections offer a newer approach that can provide relief for up to a month without interfering with other medications. The cost varies based on body weight, and while more expensive initially, many owners find the convenience and effectiveness worth the investment.
Dietary solutions and management
Switching to hypoallergenic or novel protein diets can help manage food allergies effectively. These diets use proteins your dog hasn't been exposed to previously, reducing the likelihood of allergic reactions. The transition should happen gradually over 7-10 days to avoid digestive upset.
Some owners have reported success with brands like Wild Earth, which offers high-quality, allergen-friendly formulations that have shown improvements in skin health. The key is finding a diet that eliminates known triggers while providing complete nutrition.
Keep a food diary during dietary trials. Note what your dog eats and any symptoms that develop. This information helps identify patterns and provides valuable data for your veterinarian to review.
Grooming and topical treatments
Weekly bathing with hypoallergenic shampoos can significantly reduce allergen accumulation on the coat. Medicated shampoos help soothe existing skin irritations while removing environmental allergens before they can cause problems.
Anti-inflammatory wipes offer a convenient way to clean paws and faces after walks, removing pollen and other allergens before they can trigger reactions. Focus on areas that come into direct contact with grass and plants.
Regular brushing helps remove loose hair and trapped allergens, but be gentle if the skin is already irritated. Some dogs benefit from having their coat trimmed shorter during allergy season to reduce allergen contact.
Prevention and long-term management
Environmental control makes a significant difference in managing allergies. During high pollen days, limit outdoor time during peak hours, typically early morning and late afternoon. Wipe paws and faces after every walk, and consider using air purifiers in your home.
Monitor symptoms consistently and keep a journal noting triggers, weather conditions, and symptom severity. This information helps identify patterns and guides treatment decisions. Many owners discover their dog's allergies follow predictable seasonal patterns.
Regular veterinary check-ups allow for early identification of developing allergies and adjustment of treatment plans as needed. Your vet can provide personalised advice based on your dog's specific triggers and response to various treatments.
Managing allergies requires patience and often involves trying different approaches to find what works best for your individual dog. The combination of appropriate medical treatment, environmental management, and consistent grooming typically provides the best results for long-term comfort and quality of life.
