1. You have to make it physically impossible for your dog to gobble their food by using a slow-feed bowl. It will slow down the eating procedure by more than seven times!
2. If you cannot buy a slow feeder dog bowl, just put a toy ball in the food. That can help him slow down as he cannot take big bites of food, but he has to bypass the ball.
3. Never use a deep feeding bowl. If you use a shallow bowl, he is not able to take a big mouth full of food.
4. Feed your dog multiple times a day and always give small portions. Refill a minute or two after he finishes. It may take mealtime longer, but it is best for your dog.
5. Always choose large-grain dog food. It is too easy to swallow the smaller grains without chewing, and it is also dangerous as they can cause drowning. On the other hand, your dog has to chew the larger grains, which takes time.
6. Since these guys seem to be always hungry, you can give him/her some healthy snacks during the day: some carrots, millet balls, or even a large chew bone that s/he cannot eat, only chew.
