Our 4 month old GSD, Kaiser, was running around with us and his rear paw fell down in a storm drain grate. He hopped right up but and was babying it for a bit. I laid him down to relax for a bit and is now up running around fine now. He does have a scrap on his leg about an inch long. We plan to take him to the vet tomorrow to check him out but would putting a little Mycitracin hurt anything? He let us clean it out with some soapy warm water and I would like to put the Mycitracin on it if it helps.
