I'm glad the vet thinks it's healin up good. We had a German Shepherd that was boarding at the vet jump on the chainlink fence and ripped out THREE of his nails. Poor guy. I hated having to tell the owners, but fortinatly they had boarded with us before and understood it was an accident.

Interceptor can be a bit pricey. Atleast your pups will be heartworm free!
