Bad luck in 3's

Took dogs to boat beach today. Buster got into trouble three times. First time he got a bit of heather stuck on his right paw. Second time he got a piece of rose bush stuck on his chest. We both expected a third thing and when he jumped down from the bench we stopped at he twisted his front right paw and limped home. It's got worse and we've given him some aspirin to help but hopefully he'll improve by the morning. Don't know why but supposed to be major storm tonight.
