Questions & Answers

16 Customer Questions


What is the difference between Chicken meal and chicken? Benefits?

Answer by ChewyAug 13, 2019
Chicken meal is rendered chicken meat that has been dried and ground up, and includes clean flesh, skin, and/or accompanying bone. But if you see a bag of dog food that proudly states it’s made with “Real Chicken,” it’s referring to a clean combination of chicken flesh and skin. Chicken meal does not contain feathers, heads, feet, or intestinal contents. Chicken meal is safe and nutritious for your dog

Change in senior dog's energy

This was the first time I have changed my dog's food in many years, he is a large senior dog and the vet recommended I change his food to something that includes grains. I also wanted to search for a food that catered to large dogs, as well as seniors. He loves the taste and his stomach handled the transition very well. His energy already seems to have improved, and he is running again in the yard. He has arthritis and IVDD so he has not had this much movement in about a year, so I am very happy with the quality of this food, it is worth the huge price jump in my opinion.

Cassie was on Large Breed Adult and I wanted to switch to Senior-she is 11. I took 2 weeks to switch and her poops were wetish and sticky (to the cement). I had to put her on Proviable to get them to the regular consistancy. Now they both love the food!

She loves it!

Our dog Elvira normally takes awhile to get used to new food, but this one she devours as soon as it is put in her bowl.

I love Hill's products so got this for our foster dog and continued to use it once we adopted her. She's a senior large breed that we think is about 7. She does great on it - her weight, muscle mass, skin and coat are all improved.

New Food

The girls seem to have adjusted well to the new food. They seem to like it bowls are always left clean.
