I hope the yogurt works! We are dogsitting another greyhound right now, and her family warned us about her terrible gas. Sure enough, the gas was CONSTANT for the first day we had her here. We started giving her the yogurt, and the gas is now a mere occasional distraction! I swear by the stuff - from my viewpoint, it is a Godsend! I've also heard that non-flavored canned pumpkin can cut down a dog's gas problems, but I've never tried it. As for the snacks, our dogs get the usual crunchy milk-bone type treats, but they also love their veggies! They get a couple of spoonfuls of non-salted canned veggies with dinner, and occasionally as treats. None of our dogs get table food... except when I'm making a salad. I can be cutting up a steak in the kitchen, and they all ignore me, but if I cut a head of lettuce, they are all right there by my side, waiting for bits of lettuce, carrot, celery, etc.
P.S. Can anyone give any more input to the thought that dairy is bad? The yogurt thing is a tried and true trick used by many of the greyhound owners in our area, and so we've done it with all our dogs - with the complete support of our Vet! We haven't seen any adverse reactions in the year and a half we've done it, but if there is evidence pointing to long-range problems, I'd stop! Any more insight?
