This episode explores itchy skin in dogs, how to tell when scratching becomes a problem, the most common causes, and why proper diagnosis is essential. It covers parasites, allergies (contact, food and inhaled), secondary infections, treatment pathways, and long-term management strategies to keep dogs comfortable.
Podcast Summary: Understanding Itchy Skin in Dogs
- Occasional scratching is normal, but red skin, hair loss, chewing or constant scratching suggests a true skin problem.
- Location of itching matters — belly, armpits and groin often suggest contact allergies, while feet and ears are common in food and atopic allergies.
- Fleas are one of the most common causes of itch, including flea allergy dermatitis which can occur even with very few fleas.
- Mites such as sarcoptic and demodex mites are microscopic and require veterinary testing to diagnose.
- Allergic dermatitis is extremely common and includes contact allergies, food allergies and atopic dermatitis (inhaled allergens).
- Food allergies are relatively uncommon and require a strict 6–8 week elimination diet trial for diagnosis.
- Atopic dermatitis can be diagnosed through blood allergy testing or intradermal skin testing by a veterinary dermatologist.
- Some dogs benefit from desensitisation immunotherapy, with 60–70% showing significant improvement.
- Secondary bacterial and yeast infections commonly develop due to scratching and must be treated alongside the primary cause.
- Fish oil (Omega-3) supplementation can help reduce inflammation and support skin barrier health.
- Medicated shampoos and leave-on conditioners may help support skin health but do not cure underlying allergies.
- Allergic conditions often worsen with age and may begin seasonally before progressing to year-round issues.
- Persistent foot chewing is rarely a habit — it usually indicates ongoing itch or infection.
- Diagnosis often requires ruling out parasites first, then working through allergy testing if symptoms persist.
