Gone to the dogs
Things have really gone to the dogs with this stag do activity!
Treat the stag and the lads to an evening's entertainment at the local greyhound track. With your drinks and food all thrown in, you might even win a little bit of cash if your dog-whispering skills are up to scratch! The stag can even have a race named after him, going down in greyhound racing history forever.
For a stag activity you can bet on, greyhound racing is a "bone fido" winner.
