Man’s best friend is as treat-obsessed as we all thought.
In a recent study conducted by psychologists at the University of Florida, 90% of dogs opted for food over their favorite toys. During the experiment, which mirrored a training scenario, the dogs were given a choice between their favorite food and favorite toy. The majority showed a greater inclination towards the food reward.
“I was surprised, but nobody’s looked at how dogs will work for toys versus food before,” said Nicole Dorey, a lecturer in the UF Department of Psychology who performed the study with her students and other collaborators.
The researchers recruited 10 pet dogs from the local area. Each dog was shown six food items – including treats, cheese, carrots, and hot dogs — and six toys, such as a tennis ball, a squeak toy, a plastic bone, or a stuffed animal. Each dog then had a chance to choose their favorite food and favorite toy.
In another set of experiments, the dogs had to work harder and harder for their reward. Most dogs gave up earlier when offered a preferred toy reward than when given their favorite treat.
Other studies have shown that dogs might prefer human attention to food.
“I think the next study should look at all three – attention, food, and toys – and what dogs really like best when training,” Dorey said.
Some dog trainers suggest using toys instead of food in training to avoid excess calories and to make the experience more fun for the dog. If dog owners want to follow this advice, the key is to not have toys competing with food, say the researchers.
“You can definitely train your dog with toys if you start really early,” Dorey said. “This is what’s done with search and rescue dogs, they start really early with toys as a reinforcer.”
