Mouth Sores

Mouth sores are more common for older dogs who might have other illnesses such as kidney disease or diabetes. Dental disease can also be a reason for causing mouth sores, both of which can cause your dog to excessively drool.

Proper dental care is essential to keeping your dog healthy and preventing mouth sores.

Tips for cleaning your dog’s teeth can be helpful if this is something that you struggle with. Also, if you have a dog that is hard to keep still for a teeth cleaning, you might want to consider using an ultrasound toothbrush for your dog.

Mouth sores will often times cause dogs to drool or paw at their mouths. They may refuse to eat because it hurts too much, and they may sit in front of their bowls and cry.

Mouth sores need medical attention to treat the underlying cause of the problem, and are extremely painful for your dog.

There is some first aid that you can provide to relieve the pain and keep your dog eating, but you should seek treatment from your veterinarian as well.

Give A Topical Treatment: Using an over-the-counter pain reliever like Anbesol is a great way to reduce your dog’s pain. Dip a cotton swab and dab it directly on the sores in your dog’s mouth.

This is perfectly safe to use on your dog for a day or two.

Give your dog crushed ice. Dogs generally like ice and it will provide some relief.

You can also rinse your dog’s mouth with a saline solution to help speed up the healing. This will keep the mouth clean and promote healing. Nolvadent for dogs is a great one to use.  It works at preventing infections but also has a numbing effect and helps relieve mouth pain.

Another product that you could use on mouth sores is an over-the-counter product that contains lidocaine. This is a topical anesthetic that deadens feeling. Solarcaine for humans, works well. Apply Solarcaine to a cotton swab and dab it on the mouth sores for temporary relief.
