We have two 13 week old Lurcher pups. In a fight over food, one of the pups has suffered a puncture wound to the top of the left shpulder leaving him him with a hard plum shaped lump which was sore to touch at first. Swelling reduced but still there. Can hold the swelling and move it about without hurting the dog. We're new to Lurchers, although experienced with Terriers. Pelt clearly different. The Lurcher pup seems fine. Lively, loves his food, just concerned aout the remaining swelling. Any advice gratefully received.
