If your dog is constantly scratching and biting himself, it can be concerning. While occasional itching is normal, excessive scratching, licking, or biting may indicate an underlying health issue. Let’s explore the common causes and what you can do to provide relief for your furry friend.
Common Causes of Excessive Scratching and Biting
1. Fleas and Ticks
Fleas and ticks are among the most common culprits behind excessive itching. Flea bites can trigger an allergic reaction, leading to severe discomfort. If you notice tiny black specks (flea dirt) on your dog’s fur, it’s a strong indicator of an infestation.
Solution: Use flea and tick prevention treatments like Seresto Flea and Tick Collar or vet-approved spot-on treatments.
2. Allergies
Dogs can suffer from food allergies, environmental allergies (pollen, mold, dust mites), or contact allergies (certain fabrics or cleaning products). Symptoms include red, irritated skin, ear infections, and excessive licking of paws.
Solution: Conduct an elimination diet to identify food allergies or consult your vet for allergy testing. Consider hypoallergenic dog food like Hill’s Prescription Diet for dietary management.
3. Dry Skin
Cold weather, low humidity, and over-bathing can cause dry, flaky skin, making your dog itch and scratch excessively.
Solution: Use a moisturizing dog shampoo like Oatmeal & Aloe Shampoo and add omega-3 fatty acids to your dog’s diet for healthier skin.
4. Skin Infections
Bacterial and fungal infections, such as yeast infections, can cause severe itching, redness, and a foul odor.
Solution: Your vet may prescribe antifungal or antibacterial shampoos and medications to clear up infections.
5. Parasites (Mange and Mites)
Sarcoptic or demodectic mange caused by mites can result in intense itching, hair loss, and crusty skin.
Solution: Seek veterinary treatment, as mange requires prescription medication to eliminate the mites.
6. Anxiety and Stress
Dogs may chew or scratch excessively due to anxiety or boredom. This behavior is common in dogs suffering from separation anxiety or lack of mental stimulation.
Solution: Provide interactive toys, daily exercise, and calming aids like Adaptil Calming Diffuser to ease anxiety.
When to See a Vet
If your dog’s itching persists despite home remedies, consult a veterinarian. Persistent scratching can lead to open wounds and infections, which require medical attention.
Excessive scratching and biting in dogs should not be ignored. Identifying the root cause and implementing the right treatment can ensure your dog remains happy and itch-free. If unsure, always seek professional veterinary advice.
