Is Wellness CORE Original good for large dogs?

Yes. It is formulated for adult dogs including large breeds, with calorie-dense kibble and added glucosamine and chondroitin for joint support. Feed to the bag's weight chart and adjust for activity.

Is it completely poultry-free?

No. Turkey is the lead ingredient, but the recipe also includes chicken meal and chicken fat. Dogs with chicken allergies should look at a single-protein or limited-ingredient food instead.

How does it compare with Wellness Complete Health?

CORE is the grain-free, higher-protein line; Complete Health uses grains and is generally gentler on sensitive stomachs. Choose CORE for a meat-first formula and Complete Health if your dog does better with grains.

Does it contain grains?

No. It is grain-free, using peas, potatoes and chicory root for carbohydrate and fiber. That suits some dogs, but owners worried about grain-free diets should discuss it with their vet.

How should I switch my dog onto it?

Transition over about a week, mixing increasing amounts of CORE into the old food. Dogs with sensitive stomachs may need a slower switch, and stop if vomiting or diarrhea persists.
