Transformation

I recently adopted a rescue who is overweight and has behaviors which can be attributed to nutrition deficiency. I trust Hills. It’s what all my dogs eat through

I recently adopted a rescue who is overweight and has behaviors which can be attributed to nutrition deficiency. I trust Hills. It’s what all my dogs eat through each stage. Toni will be three on January 20th. Here’s to many more returns. The transformation will take time, but I can see the difference six months has made. Coat, nails, behaviors - it all comes down to nutrition and consistency in training.

We swapped Macy over to this food in order for her to loose weight. We went by the recommendation of our vet and so far she has lost 5lb. She is getting old and doesn’t have many teeth left, for the tiny bites are perfect for her. She loves the taste of the food too!

Chewy Rocks

Thank you Chewy for helping me get out from under mistakenly way over ordering Science Diet Oral Health for small dogs. It's an excellent product that our dog likes

Thank you Chewy for helping me get out from under mistakenly way over ordering Science Diet Oral Health for small dogs. It's an excellent product that our dog likes. But she is 12 year old and weighs 8 pounds. Four pounds of the oral diet lasts a l-o-n-g time for her. The extra food went to Bread of the Almighty, our local food bank. We all thank you!

My fur baby is 15 years old . I have been feeding Hills Science dog food +11 years for more than 4 years. Gizmo is a small Shiz tu weighing only 10 pounds. He loves the food . He has maintained a good weight and is still an energetic dog. I started him on this food on the advice of my vet. I couldn't be happier with the results.

Small Kibble

I have a 16-and-a-half-year-old beagle who tends to choke if she eats too much. This was the perfect size for her. It came really fast, too!

Truly bite size

I like how truly tiny and bite size these are. Helped for my senior dog with no teeth when we soak his food to rehydrate so he can gum it.
