If you’re asking, “Why is my dog constantly scratching and biting himself?”, you’ll find the answer right now.
Many dog owners face this frustrating issue. While some scratching is normal, constant or severe itching can signal something more serious.
In this article, we’re going to discuss the most common reasons dogs scratch and bite themselves. We’ll also cover how to address the problem and keep your dog comfortable.
Common Causes of Scratching and Biting in Dogs
There are several reasons your dog might be scratching and biting at his skin. Let’s take a closer look at the most common causes.
1. Fleas and Parasites
Fleas are the #1 cause of itching in dogs. If your dog is scratching and biting himself, fleas are likely the culprit.
These tiny insects can irritate your dog’s skin, causing discomfort. Other parasites like ticks, mites, and lice can also cause similar symptoms.
Look for signs like flea dirt (tiny black specks) in your dog’s fur. If you notice your dog scratching more than usual, it’s time to check for fleas.
2. Allergies
Dogs can develop allergies just like humans. Environmental allergies are common, especially with pollen, mold, dust mites, or even grass.
Food allergies can also cause itching and irritation. If your dog scratches after eating certain foods, it could be related to an allergy.
Contact dermatitis can occur if your dog comes into contact with irritating substances like detergents or certain grooming products.
If you suspect allergies, you may need to change your dog’s diet or environment. Talk to your vet for advice on managing allergies.
3. Dry Skin
Dry skin can make your dog itch, and this is especially common in winter months or in dry climates.
If your dog’s skin looks flaky or feels rough to the touch, dry skin might be the issue. It can also happen if your dog isn’t drinking enough water or isn’t getting the right nutrients from his food.
If your dog’s scratching is due to dry skin, moisturizing baths or humidifiers in the house can help. Make sure your dog’s diet includes enough omega-3 fatty acids for healthy skin.
4. Skin Infections
If your dog is constantly scratching and biting himself, it might be due to a skin infection. Bacterial or fungal infections often follow when a dog scratches or licks too much. The affected areas can become red, swollen, or even oozing.
Infections can be painful for your dog and may require antibiotics or antifungal treatment. If you notice signs of infection, it’s best to visit the vet for proper care.
5. Hot Spots (Acute Moist Dermatitis)
Hot spots are inflamed, itchy areas that develop when a dog scratches or licks repeatedly. These can be painful and may look like red, raw patches of skin.
Hot spots often occur when a dog has an underlying issue, like allergies or parasites.
If you notice your dog developing hot spots, it’s important to get them treated quickly. Left untreated, hot spots can become infected and worsen.
6. Underlying Medical Conditions
Sometimes, excessive scratching and biting are signs of an underlying health condition. Hormonal imbalances like hypothyroidism or Cushing’s disease can lead to skin problems. Autoimmune diseases or other systemic issues might also cause chronic itching.
If your dog’s itching is persistent and unexplained, a veterinary exam can help rule out any serious medical conditions.
Diagnosing the Problem
Wondering how to figure out why your dog is constantly scratching and biting himself? The first step is to consult your veterinarian.
Your vet will perform a thorough examination, possibly including skin tests, blood work, or allergy tests. A proper diagnosis will help determine the root cause and guide treatment options.
If your dog’s scratching is accompanied by hair loss, wounds, or swelling, it’s especially important to see a vet right away.
Treatment Options
Once you identify the cause, you can start treating the issue and help your dog feel better.
1. Flea and Parasite Control
If fleas or other parasites are causing the problem, flea treatments are your first line of defense. Topical treatments, flea collars, and oral medications can eliminate fleas and prevent future infestations.
Your vet can recommend the best product for your dog.
2. Managing Allergies
If allergies are to blame, you might need to make some lifestyle changes. For environmental allergies, try to limit exposure to allergens, such as pollen or dust.
If food allergies are the issue, a special hypoallergenic diet may help. Your vet may also prescribe antihistamines or steroids to reduce itching.
3. Skin Care and Moisturizing
To treat dry skin, give your dog moisturizing baths using dog-friendly shampoos. Look for products with oatmeal or aloe, which soothe itching.
Adding omega-3 fatty acid supplements to your dog’s diet can also help improve skin health from the inside out.
4. Treating Infections
If your dog’s scratching is due to a bacterial or fungal infection, your vet will prescribe the appropriate medications.
This may include antibiotics, antifungals, or topical treatments. Be sure to follow your vet’s instructions for application and duration.
5. Addressing Hot Spots
For hot spots, it’s crucial to clean the area regularly and apply prescribed ointments to reduce inflammation. Y
our vet may also recommend an Elizabethan collar (cone) to prevent further licking or scratching.
