You're probably right. My current dog is food hound first, guard dog second. We have to monitor what we give him as he'll eat everything in front of him. I've never had a dog like him as far as food goes. The dog we raised who's currently with my daughter will eat half a bowl and come back later to finish it off. Oto (the dog we now have) will finish a bowl in less than 2 minutes and then spend the next 5 minutes circling the floor looking for dropped crumbs. No, he doesn't have tape worms LOL.
LOL! My dogs had no clue when to stop eating if it was people food. Once, my wife was loading them up, and I told her as much. She kept right on. About 30 seconds later, Brownie tiptoed away from the pack into the other room and within 3 - 5 seconds came right back in for more. I "knew" something was up. I looked in the other room, and he vomited everything out to make room for more.
LOL!!!!!!
We had a Newfoundland puppy once named Schultz. When he was about 3 or 4 months old, we had a little food issue also. My wife and I had left the house to go somewhere. When we returned, we found him laying on the floor on his side with his stomach so distended you could bounce a quarter off of it. He had chewed through the side of the puppy food bag and eaten till he couldn't eat any more. I thought he had committed suicide by food. He laid there and didn't move for hours but would belch occasionally. The next day after he was up and around, he crapped pile after pile after pile.
