1. Allergies: Allergies to food, environmental allergens (pollen, dust mites, etc.), or even flea saliva can cause intense itching, leading to bald spots and rashes.
2. Flea/Tick Infestation: Even with flea treatment, some fleas or ticks may remain and cause skin irritation. Check for any parasites on your dog's skin and fur.
3. Skin Infection (Bacterial or Fungal): A skin infection caused by bacteria or yeast can lead to bald patches and rashes. These infections often require antibiotics or antifungal medication.
4. Mites: Ear mites and Demodex mites (mange) can also cause itching, hair loss, and skin lesions.
5. Autoimmune Disorders: Certain autoimmune diseases, such as Pemphigus Foliaceus, affect the skin and lead to blisters, crusting, and hair loss.
6. Hypothyroidism: An underactive thyroid gland (hypothyroidism) can cause a variety of skin issues, including itching and hair loss.
Recommended Actions:
- Consult a Vet: Given your dog's severe itching and the appearance of red bumps, it's essential to consult a veterinarian for a proper diagnosis.
- Skin Assessment: The vet will perform a skin examination, possibly including skin scrapings or biopsies, to determine the root cause of the problem and rule out potential underlying conditions.
- Treatment Plan: Depending on the diagnosis, the vet will prescribe appropriate treatment, which may include medications (e.g., antibiotics, antihistamines), medicated shampoos, or dietary modifications.
- Regular Grooming: Keep your dog's coat clean and well-groomed to maintain overall skin health and prevent worsening of skin issues.
- Close Monitoring: Monitor your dog's condition closely and follow the veterinarian's instructions. If symptoms persist or worsen, prompt follow-up is crucial.
