Today I went to the dog park with one of my friends and his dog. There were a lot of pups there and they were all playing well together. Later a lab came over who was around 2 years old. His owner had him on a leash and I could tell that he wasnt very socialized. 3 or 4 dogs my 16 week old German Shorthair included went over to sniff him. I started walking over to him, to pull him away from the lab, because his owner grabbed the labs snout. Before i could get to him, the lab snapped at my pup and nicked his ear. He actually severed a blood vessel in his ear, and is currently at the vet getting it repaired. I was wondering if this will cause my pup to not want to be around dogs. Also what might be the best way to reintroduce him to other dogs without him being scared. Any help would be much appreciated.
