I have 3 piggies, all 3 males, 2 of which are approximately 10 months old while the other is about 4 months old. One of the 10 month olds, Caramel, has wounds all over his lower body. I had no idea until I noticed a small wound in one of his callicks, and only upon shaving the area did I notice more. There has been no noticable changes in appetite, drinking, sleeping, etc. He does occasionaly fight with the older pig, which is a recent development that I attribute to (hopefully) teenage years. My question is whether these look self inflicted or not. They are only in areas he could reach, and some look fully scarred over, even though they only started fighting in the last month. I will include an image. I have have cream and pain medicine from a guinea pig injury that happened months ago. The white-appearing stuff is the cream i applied from the last vet visit. Any advice would be helpful
