I got a mt cur also.TCICON gave you some excellent advice.Another thing is if you can get someone to catch you a live squirrel in a cage trap that is excellent.Let the squirrel out and hold the dog back till the squirrel gets out.Then let the dog get at him.Just get your pup in the woods and work him.Possibly put out some squirrel feeders to bring your dog to them and let him get the scent.If you need anymore help let me know.
