We have a 9 month old pittie/shepard mix. However, he can't take five steps without burping. I grew up with German Shepards and NEVER saw this much gas coming out of a dog's mouth! He doesn't fart so much, but the belching is RIDICULOUS! We have to laugh at it, because even his lips flap open as if he was a cartoon animal, but could it be something more?
He is only a puppy still so two meals would be better, but just do it all the time.Its a long time to go without feed ,I have always fed my dogs twice a day and add vegies for bulk plus grated apple and carrot.
Sometimes I buy some big shin bones for them to chew on they love that.
