In a national survey conducted by Harris Interactive for Wellness Natural Petfood , owners of dogs with food allergies are confused about how to treat them.

Fewer than half of the pet owners surveyed recognized which ingredients can aggravate their pets' allergies: 40% were aware of wheat causing potential allergic reactions and 26% were aware of soy.

Wellness has introduced additions to its Simple Food Solutions hypoallergenic line of dry food to cater to pets with such allergies.
