Why dogs and cats refuse new food (and vets’ tricks to convince them)

By Dr. Kyle Muller

Refusing a food you have never tried before is not just a “whim”, but can hide a discomfort. From the blue bowl for dogs to the use of nutritional yeast for cats, here are tips for introducing new foods without stress.

They come, look at the bowl, look at the owner and leave without eating anything. They are not too selective: it is a manifestation of discomfort that can hide gastrointestinal problems or, simply, a bad relationship with food.

Tricks to entice the dog

In the case of the dog, some small tricks can help us introduce him to a new food: “If he is used to always eating in a specific part of the house, move the bowl to another room”, gives the example of veterinarian Sara D’Agostino.

The importance of colors for the dog’s vision

“Or you can exploit the colors it perceives in its visual spectrum.” In this case, a blue bowl that contrasts with yellowish morsels is better than going for red or green shades that the animal does not perceive.

How to overcome cat mistrust

For cats the situation is a little different, because by nature they are wary of new things. Adding nutritional yeast can make a dish more appetizing and get you used to the flavor of a new food, advises Barbara Tonini, president of Siana.
