I just got off the phone with the vet. They said Charlie is recovering nicely and should be ready to go in about an hour. They have to send him home with an e-collar because he'll probably want to chew on his food. The vet said that the toenail had a pretty strong odor, so the infection was pretty bad. Good thing we had it taken care of! Other than that, everything went well. :)
I'm off to the grocery store and then to get my pup!
