What is Itching His Mouth?
If you have noticed your dog scratching at his mouth and rubbing his muzzle, you may need to do some investigation to discover why he is so itchy there. While he may scratch to relieve the itch, incessant scratching can cause trauma and secondary bacterial infections in the skin. Constant scratching and pawing can also result in patches of hair loss, sore and inflamed skin, and scaling and thickening of the skin. Reasons your dog may scratch at his mouth include:
- Contact irritant
- Dental problem
- Skin condition

Why Itching His Mouth Occurs in Dogs
There are many reasons why your dog may be pawing at his mouth. Often, there is an underlying skin or other health problem which is causing the discomfort.
There are many things that can cause an allergic reaction resulting in skin irritations, peeling, and itching. Your dog may have environmental allergies, such as to pollen or dust mites, or to chemicals, such as the detergent used in washing his bedding. Your dog can develop sensitivities to the plastic of his food or water dishes, or even to the food itself. Allergies to a food ingredient are common in diets that are fed continuously over a long period of time.
A dog’s skin can also become inflamed, itchy, and sore when it comes into direct contact with an irritant. This could be a poison, such as those found in cleaning products, or from ingestion of an irritating plant, such as poison ivy or hyacinths. With some irritants, only one exposure may be needed to cause a reaction. Often, a rash occurs which can leak fluid, develop into blisters, or change color.
Often, dental pain, abscesses, and periodontal disease can cause your dog to paw at his mouth, rub his muzzle after eating, or even try to get at his ears. Skin irritation can occur from the pawing and scratching, which can lead to a mistaken case of allergies. Tooth and gum problems also can cause changes in your dog’s eating habits, bad breath, drooling, and bleeding gums.
Wounds and injuries to the mouth, tongue, cheeks, or lips can occur that can swell those sensitive tissues. The many foreign objects that dogs eat, such as twigs, can cause cuts and abrasions, or become lodged in the mouth. This will cause your dog to claw at his mouth, cough, or cry out. Even a tough bone can result in mouth and gum damage. If these types of trauma are not treated, they can result in abscesses or infections. Tumors in the mouth can also cause these reactions, and may affect your dog’s normal eating habits.
Infections can be caused by bacteria, fungi, viruses, or parasites, such as mites or fleas. These types of infections could cause skin irritations that become itchy, causing your dog to scratch. Sarcoptic and demodectic mange caused by mites both result in severely itchy skin, scabbing, and hair loss. Fleas can cause your dog to scratch incessantly, and can become exacerbated if your dog has an allergy to flea bites. Bacterial infections are common in skin that is being damaged by trauma, such as scratching.
There are other conditions which can cause the skin to become irritated and itchy. Tumors, cysts and warts can cause your dog to paw at himself. Hormonal imbalances can induce skin reactions, diseases such as Cushing’s disease or hypothyroidism may induce itchy skin. Cancer and autoimmune diseases, such as lupus or pemphigus, can also affect the skin. Dry skin and dandruff will cause itchy skin as well.
Dogs with digestive problems, or those experiencing stress or anxiety, can be affected by heartburn or acid reflux disease. The unpleasant burning in the throat and chest can cause your dog to scratch under his jaw. Other symptoms may include an increase in drinking, panting, and eating, coughing, or eating grass.
What to do if your Dog is Itching His Mouth
If you have witnessed your dog pawing continuously at his mouth, do some investigating of the area. Look for signs of skin irritations and rashes, or look in his mouth for infections or blood. Your veterinarian will ask for your observations of any symptoms in your dog, so include changes in eating, elimination habits, and behavior. Your vet may also ask if your dog has been in contact with infected animals, if you have noticed fleas, if he has eaten something he shouldn’t have, or if there is something new in his environment, such as a new diet, shampoo, or cleaning product used in areas he frequents.
After a physical examination, your vet may also perform a thorough dental exam to determine if there is a dental issue causing the scratching. Further testing can include blood, urine and fecal tests to look for infectious agents, X-rays or ultrasounds if there may be a tumor or tooth issue, skin scrapings, allergy testing, or an endoscopy to examine the esophagus. Once the cause has been determined, treatment follows as needed.
Allergies can be controlled with medications, such as antihistamines and steroids, a removal of the allergen which may require a change in diet, and possibly allergy shots that can help to desensitize the immune system. Dental problems may require oral surgery to remove teeth, treat abscesses, and clean the teeth and gums. Dental surgery may also be used to treat any trauma in the mouth or remove oral tumors. Antibiotics to treat or prevent infections, and pain medications, can be prescribed after such procedures. Parasites are often treated with specialized medications, and you may be given certain shampoos or lotions to apply to your dog to remove them. Bland, moist diets work well for dogs who suffer from heartburn, as do medications to reduce the production of stomach acid.
For healing the skin itself and relieving the itch, many of the medications given for allergies can be used. Soothing shampoos and specialized lotions and creams can moisturize and heal the skin. Be sure to monitor your dog for any changes during recovery, and keep any irritants and allergens out of his reach.
Prevention of Itching His Mouth
Preventing an allergy from developing is impossible, but you can prevent an allergic reaction by reducing your dog’s contact with the allergen. Monitor your yard for possible irritating objects and remove them so that your dog cannot eat them. Routine dental care can be accomplished at home that can keep your dog’s mouth healthy, such as regular brushing. Routine examinations are essential to catching disease early and treating your dog before symptoms become too progressed.
Cost of Itching His Mouth
The cost to treat an itchy mouth in your dog can vary considerably, depending on the cause, and can range from $200 to $3000. The average cost for a tooth abscess can average around $1200, while gum disease can be as expensive as $2500. Treatments for infections such as mange can average $350. An acute case of contact dermatitis can be around $400, while pollen allergies can be as high to treat as $1200.

My dog has been using her bed to itch her muzzle. It seems like she's trying to get something off her nose. This is the first time I've seen her go crazy, usually it's just a normal itch. Any clues?

what to do if my dogs mouth is somewhat swollen because of sudden itching WHEN SHE ATE PORK WITH SOY SAUCE SUDDEN ITCHING IN MOUTH OCCURS.. IS IT OK ? OR WHAT WE WILL DO TO LESSEN THE ITCH....SHE IS LIVELY AND NO SIGNS OF ANYTHING MORE SERIOUS OTHER THAN THOSE SHE IS NOT HAVING HARD TIME BREATHING
Soy sauce is toxic to dogs due to the high salt content; also some brands of soy sauce may have other ingredients which may be poisonous for dogs which may cause swelling, organ failure or death. In a reaction this severe, it is important to induce vomiting with 3% hydrogen peroxide to make Snowee vomit and to wash out the mouth thoroughly; it would still be best to visit your Veterinarian and take the soy sauce bottle with you to show the ingredients list.
