Lip Sores
I have a 1
1/2 year old Brittany. I noticed on Friday that he had a small
blister-like thing under the area of his bottom lip. I noticed on
Saturday there were a few more and on Sunday they were bigger and
bleeding a little. There are about 5 round sores now. What could this be?
Blisters on the lip usually indicate a contact irritant. Your Brittany may have bitten something irritating to his mouth. English Ivy, Nettles, and other plants can do this. He may have an allergy to something in his environment. His food is unlikely, for the same reaction would have occured in his stomach, and he would have vomited if it were eaten.
Sometimes the mucocutanous junctions found on the lips, anus and nose blister as a manisfestation of a systemic immune response. Certain viruses, some autoimmune diseases and other less common problems can cause this. If the problem worsens, spreads to the nose and anus, consider these other possibilites. If it occured only once, possibly repeating occassionally, then you need to hunt down the substance he is getting is mouth into and elimanate it.
