Gem had 2 good sized sores on his lower lip. One was around the size of a dime (maybe smaller) and the other one was like the size of an eraser on a pencil. I got alarmed and checked Vega and she had a very tiny one on her bottom lip, and then upon further investigation, she had another tiny one on her upper lip.
What exactly is this?
Could it be from them eating grass now?
What can I do to treat this?
Should we call out a vet?
Gem's looks a lot worse compared to Vega. It looks to be swollen behind it (if that's possible) but he is eating and drinking just fine.
Could it be similar to a cold sore?
