Pet Dogs Prefer Food Over Toys, New Study Shows | Sci.News

In a University of Florida-led study, scientists allowed pet dogs (Canis lupus familiaris) to pick their favorite food and favorite toy, then put them head to head in an experiment simulating a training experience; 9 out of 10 dogs responded more strongly to the food reward.

Lazaro et al. aimed to compare the reinforcing value and efficacy between food and leisure stimuli for domestic dogs by comparing rates of behavior when receiving access to either their top-preferred food or leisure items. The results indicate that, overall, dogs exhibit a stronger preference for and food is more likely to function as a reinforcer than leisure items for domestic dog’s behavior. Even when dogs had equal preference for both types of stimuli in preference assessments, they showed a higher response rate when working for their preferred food during progressive-ratio trials.

“I was surprised, but nobody’s looked at how dogs will work for toys versus food before,” said study’s senior author Dr. Nicole Dorey, a lecturer at the University of Florida.

For the study, Dr. Dorey and colleagues recruited and tested a total of 10 pet dogs.

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,” Dr. 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.

“You can definitely train your dog with toys if you start really early,” Dr. Dorey said.

“This is what’s done with search and rescue dogs, they start really early with toys as a reinforcer.”

A paper on the findings was published in the journal Animals.
