My dog's eye is red. Is it an ulcer on the white part or conjunctivitis?

Pet's info: Dog | Pug | Female | spayed | 7 years and 10 months old | 14.5 lbs

Hi why do vets only check the cornea for ulcers ? If the dog scratches the white part of the eye can an ulcer develop from that or is it limited to the cornea ? Therefore if the white area is pink it's probably conjunctivitis?

Thank you for submitting your question regarding Lily. Corneal ulcers are treated differently than allergic eye disease and eye infections. The results of the eye test dictates which medications can be used. The white part of the eye turning red just indicates irritation to the eye. This can be the due to almost any condition that affects eye (an ulcer, infection, dry eye, a foreign body, glaucoma or uveitis). A scratch can occur on the white part, but is more serious if it affects the cornea. I hope this information helps!
