I took CJ and Stella to visit with one of our friends and his GS/? mix attacked CJ causing a tear on his bottom lip and under his bottom lip. I had never seen so much blood. It was all over my hands, my pant leg and my shoes. I instantly called the vet and put pressure on the sites which stopped the bleeding. Since yesterday I have treated the sites with antibotic cream. CJ's entire attitude changed and he has been much more attached to me and my husband since. Should we be concerned about long term issues with other dogs? We started having him around familiar neighborhood dogs today with no noticable problems.
