Anyone know where I can buy a fly or mosquito net to fit over my dog's head? OR What do you do to protect your dog's face from flys?

Buy a pump action repellent spray from a pet shop or vet. Spray the dogs body, underneath its neck/chin & carefully on top of its head.

Thanks for the info, Keith and Judy. I guess fly spray is the one to use but is there a better spray, say with other repellants in it?
