Was talking to a friend the other day and she said that she never gives her dog pork because dogs can't digest it properly. I asked her why she thought that dogs couldn't digest pork and she said it was because it's not a natural foodstuff for dogs. Her argument is that dogs don't catch pigs in the wild. I said that dogs have been domesticated for thousands of years so they must have been fed pork at one time or another! Can anyone settle this argument please?
