Causes of Excessive Scratching in Dogs
Let’s look at some of the common causes of excessive dog scratching.
Allergies
According to studies, allergies are a common cause that triggers excessive scratching in dogs. Many dogs are sensitive to environmental allergens like pollen, mold, grass, and dust, as well as certain food ingredients. When exposed to an allergen, a dog’s immune system can trigger an inflammatory response that may result in itching. Dog skin allergies can be managed with the help of anti-allergic treatments.
Hot Spots
Hot spots are areas of inflamed, irritated skin that can develop for several reasons, including allergies, moisture, and self-trauma. They can cause significant itching and discomfort in dogs, often leading to self-trauma like scratching, licking, and chewing. The inflammations are generally painful and sensitive. However, they can be treated with the administration of anti-itch products or antibiotics, which your veterinarian can help you with.
Bacterial Skin Infection
Bacterial skin infections in dogs can develop when normal skin bacteria multiply excessively, often in association with an underlying skin condition. It causes uncontrolled itching and is often accompanied by small red bumps and skin inflammation. To escape the discomfort, dogs end up scratching themselves excessively. Treatment depends on the type and severity of infection and may include veterinarian-prescribed medications.
Yeast Infection
Caused by the overgrowth of the fungus called Malassezia pachydermatis, yeast infection is a common skin disease in dogs that can trigger significant itching and scratching. It causes hyperpigmentation and darker skin on the armpits and groin, along with a musty odor. The infection can be managed with the administration of oral and topical antifungal treatments.
Parasite Infestations
Dogs of all breeds and ages tend to get infested with parasites like fleas, ticks, and lice. These parasites can irritate your dog’s skin and may trigger itching, inflammation, and hair loss. To relieve themselves, dogs end up resorting to self-trauma like excessive scratching and chewing. Thankfully, there is a plethora of parasitic treatments, including flea and tick treatments for dogs available on the market that help manage external parasite infestations. They work effectively to treat existing parasites and also prevent future infestations. Some of the most popular parasitic treatments for dogs include Simparica Trio, Bravecto Chews, and NexGard Chewables.
Ringworm
Contrary to its name, ringworm is not a worm infection but actually a fungal infection. It can cause itching, hair loss, and skin lesions in dogs, leading to self-trauma like scratching and chewing. The infection is contagious and can be transmitted to fellow animals as well as humans. Ringworm can be managed with oral and topical antifungal treatment recommended by a veterinarian.
Dry Skin
Itchiness triggered by dry skin is common in dogs. The condition leads to severe scratching, licking, and chewing. Dry skin can have several causes, including dry weather, environmental factors, nutritional issues, allergies, and underlying skin conditions. Also, young puppies with underdeveloped oil glands can suffer from dry skin-related itchiness. Depending on the cause, a veterinarian may recommend dog-safe moisturizing shampoos, conditioners, or other appropriate skin-care products. Besides topical products, oral supplements featuring omega-3 fatty acids may be effective in relieving itchiness in dogs.
Skin Cancer
Some skin tumours may cause irritation, ulceration, or discomfort, although signs can vary depending on the type and location. If your dog is suffering from cancer, it may show symptoms like self-trauma, scratching, oozing lesions, scabs, bumps, and hair loss. Therefore, if you notice a non-healing wound or a discolored area on your dog’s body, you should immediately get in touch with a veterinarian. Skin cancer in dogs is diagnosed with a biopsy and managed with chemotherapy, radiation, or surgery.
Common Signs That Accompany Excessive Scratching
Below are some common signs that may accompany excessive scratching in dogs.
Redness & Rashes
Excessive scratching causes significant damage to dogs’ skin, often resulting in redness, rashes, and hotspots. It generally happens when the dog’s nails create tiny abrasions and damage the outer protective layer of the skin.
Bald Patches
Repeated scratching can break or pull out hairs, especially when the dog scratches the same area repeatedly. Also, in many cases, persistent trauma and inflammation can irritate or damage hair follicles, leading to bald patches.
Behavioral Changes
Persistent itching can cause discomfort and may affect a dog’s behavior, leading to behavioral changes like restlessness, irritation, and anxiety. Frequent scratching, especially at night, can interrupt sleep, resulting in fatigue and reduced activity.
