High quality food! My dogs love this food very much. It doesn’t smell bad at all and it doesn’t have any food coloring like other foods. My dogs enjoy it but it ca be pricey so I try to buy it when it goes on sale.

Flavor Name: Chicken & Barley Size: 45 Pound (Pack of 1)
Our berner likes this but doesn’t love it. It’s really good for her & recommended by her vet though so we keep feeding it to her & put some bone broth on top!

    • My dogs love science diet.
Flavor Name: Chicken & Barley Size: 35 Pound (Pack of 1)
Long time science diet user for my dogs. Always provides great nutrition for them. They love the taste, and I love the fact that it comes in the perfect size to match the size of my dog and they’re eating patterns. (Labs). Also love that I can count on the freshness of the food and that I can Velcro the bag to continue to keep it fresh. Especially appreciate that their food is made from simple ingredients and not tons of fillers that they don’t need. This helps them live along and healthy life. ... show more

    • Healthy and beneficial for your dog
Flavor Name: Chicken & Barley Size: 15 Pound (Pack of 1)
My favorite dog food for my 4 year old blue heeler mix. She is a medium sized dog, about 25 lbs. I noticed she was gaining too much weight when we had her on Pedigree so I switched her to this. Now her coat is so much softer, and she is lean where she is supposed to be. Her regularity and poop is good too. I feel like this brand packs nutrition and quality in their ingredients so I trust it. The price point isn’t so bad either. I like the resealable bag too. ... show more
