Biscuit is under the weather

We discovered yesterday evening that it appears that Biscuit has an ear infection in his left ear.  This is the same ear where the vet discovered that Biscuit had a ruptured ear drum and a very swollen ear canal when Biscuit was first seen by a vet while he lived at the sheltie rescue after Biscuit had been living on the street.  We are taking him to the vet tonight to be certain, and get the right medicine to clear up his ear.  Poor little guy.  We hope that he will be feeling better soon.  Below are some recent photographs of Biscuit.
