I was walking my dog and he ran under a bush to chase a cat. I yanked him back and later I noticed that his pen his was bleeding. As I was cleaning the blood, I noticed a hard dark orange almost pink hard substance wrapped around his penis. I could tell it was uncomfortable for him so I began to remove it with tweezers. Does anyone know what that is? Iâ€™ve never seen it on him or on my other dog. I thought it might have been something from the bush but it does not look like a leaf or anything that would be on the ground.
