The best poo ever

My picky eater loves this food and we have had the best poos. She only poos once a day: unlike the cheap food which she is constantly hungry and having two, three

My picky eater loves this food and we have had the best poos. She only poos once a day: unlike the cheap food which she is constantly hungry and having two, three poops a day. She also doesn’t have the icky dog smell like you get from cheap food, no bad breath or the yeasty skin smells either. Because she eats less, it ends up being more economical. The old adage applies: You get what you pay for.

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 .
