The fast eaters will wolf down as much as you will give them, and then start stealing other dogs' food.
The slow eaters are picky about their menu, or just nibble at their food, or both. The slow eaters often take breaks while eating, during which the fast eaters will swoop in and gobble up their food.
At the Happy Animals Club, the founder put in place a policy of not keeping animals in cages. Dogs are free to roam around, and would normally have access to other dogs' food bowls. When feeding a pack of free-range dogs, it is a challenge to make sure that the slow eaters get enough, and that the fast eaters don't get too much.
To solve this problem, we introduced the concept of feeding bays.
Slow eaters are isolated in the feeding bays at mealtimes, ensuring that other dogs do not have access to their food.
When the dog is done eating, it is released from the feeding bay back into the dog yard.
The feeding bays have a retractable screen tray, so that any spilled food does not fall on the ground, where it will get licked up - together with a lot of dirt - by the fast eaters.
After each feeding, the feeding bay floors and walls are hosed down, and the screen tray is removed and cleaned.
The feeding bays are raised off the ground, at a height comfortable for humans. That way humans can easily monitor what the dog is doing, and provide encouragement if necessary. Some very spoiled dogs only eat if they are fed with a spoon.
