Molly i'm no expert,but i think two small meals is better than one large one.Maybe an idea to do some research (google) on whether it effects pups,i'm pretty sure it can.I think the critical thing is,time between feeding and exercise or between exercise and feeding.For me its always 5 hours,mainly because thats what my old man did,and he never had any probs with his dogs.Some people say the dog only needs to rest for an hour or two,before feeding.That may well be the case,but i'm not prepared to take the chance with any of mine.Better safe than sorry i say.Bill
