My 3 year old rottweiler is in good health and regularly run 3 miles with me 2 - 4 times per week. The other day we were about to go running and I notice blood on his left rear paw. After seeing the blood I also notice he had a slight limp. After closer examination his outer toenail seemed to be ripped and hanging by a thread or two. I did not take him running. The tonail came off a couple days later. I have some antibiotic ointment on the paw and also put alcohol on the paw on several diff days. It has been abut 1 1/2 weeks since this began. When the dog licks this paw he does it very, very gingerly. Question is: I dont have $50 for the vet visit, not to mention whatever medicines that the vet prescribes. I am still stumpped as to how this happened. The dog is in a fenced in yard. Any sugguestions? Thanks.
