Idk what this is on sketch's snout. It wasn't there last night when i was playing with them before i went to bed. His food hasn't changed and there's nothing he could get into. It looks like a pimple/blood blister. It doesn't seem to bother him cuz i can touch it with no response from him. I just want to know what it is, if i should be worried, if it'll go away or if i need to have it removed. Thank you in advance for your time and help!
