I've noticed my little guy has been grooming/biting around the genital area a lot more so after giving it a check I didn't see any hair rings but I noticed it was sticking out more and also looks swollen. Also the coloration seems very dark (I just recently returned from university so while I was gone I wasn't the main caretaker so I'm concerned something happened while I was away). Overall his actions and activities seem normal and playful. He's eating/drinking fine and pooping just as much. Also there doesn't seem to be any issues when he urinates. I plan on taking him to the vet for a check up but I was hoping to get some insight and ideas.
