Red sores on mouth.

Species: Dog
Breed: german shepard mix
Age: 11-15 years
My dog has developed sores or bubbley looking things round her mouth. They get irritated and sometimes bleed. Her lip area has also developed at bright pink pigment. I want to know if this is dangerous, and what could it be? thanks

Online vet, Dr. Marie

Dr. Marie replied:

This could be something called a lip fold pyoderma. These are really uncomfortable infections around the mouth. They need to be treated with antibiotics prescribed by the vet.

There are other more serious possibilities such as an autoimmune disease called pemphigus. but, I think a lip fold pyoderma is most likely.
