What food benefits are best for my large or giant breed dog?

I would say Joey is a large breed dog based on his mix of breeds. I recommend feeing him a high quality large breed dog food. These foods will have joint support, which is great for bigger dogs. Brands I recommend include Royal Canin, Hill's Science Diet, Purina ProPlan, and Iams. I hope this helps!

What's the best, safest, healthiest dog food for my giant breed?

I personally like Royal Canin, Hill's Science diet, Purina ProPlan, and Iams. I have fed Royal Canin and Iams to my pets (cats and dogs), and have found them to be excellent food for them. They will all have a giant breed formula. Acana and Orijen are good brands, but they are quite expensive.

My puppy won't eat Iams. What's the best healthy puppy food?

As long as it is a name brand food with an AAFCO label on it. This means it has been tested and meets specific standards. Typically royal canin, Purina, science diet, and Iams qualify for this. Be careful switching foods without suddenly as this can cause diarrhea. It is best to mix them and gradually switch it over a week

Is it time to switch my 6-month-old large breed puppy's food?

Lifetime large breed dog food is formulated for all life stages, including puppies. Since he is already 60 pounds, you can begin to transition him to this diet at any time. Please switch diets gradually by mixing the old and new diets together for 5-7 days to ease the transition.

What large breed food is best for my 9-month German Shepherd?

I use the large breed adult food from 9 months on. I like the dogs to grow a little slower to prevent bone problems. Soska will reach her full size but it will just take a little longer with less bone and joint issues. I usually mix the new food with the old food for a week or two so she doesn't get a stomach upset. Thanks for using Boop by Petco to help you care for Soska.
