I wwas walking around my house when I saw a spot of blood on my floor. At first, I thought maybe my dogs got into a fight or something while I was away. I found the source of the bleeding on the right hip area of my older dog. I know we have foxtails in our backyard (we just moved in and im still trying to find a way to get rid of them) and try to check my dogs fur frequently. I cut the hair around the wound and cleaned it with a clean wash cloth and warm water. Can this be treated at home? My dog doesn't seem to be bothered much when I touch it. Any guidance would be helpful! Thank you!!
