About 9 days ago nala got bit by a german shepard while at the dog park. She yelped badly when it happened but we didn't notice anything wrong right away. When we got home we noticed a small drop of blood on her fur (she is a yellow lab) so I looked for a mark. She had a small puncture mark on her side just behind her right front leg. I washed it really good with alcohol and did so for the next couple of days and made nala take it easy for a couple of days. Nala seemed fine and we figured it was just a little scratch. We went out of town this weekend with nala and she had a blast swam both in the pool and in the ocean both days. Today I noticed a mass where the bit mark was about the size of a golf ball. I am not sure what it is but thought maybe it is swelling from all the activity today. Our vet was closed when we noticed it so we couldn't take her in. Does anyone know what it could be? It doesn't seem to bother her. I can touch it, pinch it, and apply pressure to it and she doesn't yelp or anything. Any help would be greatly appreciated.
