Dogs LOVE it!

I have 3 Schnauzers. This oldest is 13 and is having some difficulties with his health. Has become very picky as far a what he eats. I have had to keep buying different brands just to see if they would eat it and then wind up giving the bag to neighbors dogs because they wouldn't eat it.

My Dog Is in Love!

My beagle/shepherd girl is 4 years old and never been thrilled about any of the dry food I’ve bought for her... until now. She typically checks her food and then walks away to see if something better will appear. Now that I started serving her Merrick Petcare Laci is excited to head to her food bowl and chow down. I have since purchased a new bag since she enjoyed the first one so much. Plus, I like the quality ingredients! I know my girl is getting good kibble. All opinions stated are strictly my own. I received a sample of this food to try.

Picky Dog Approved!

My pup Bear is a little over 5 years old and very spoiled. He loves food but can be picky, for example he only like certain flavors of the brand I usually feed him. but wow the second I mixed this food with his usual food he immediately went to eat the "new" food out first. I've been feeding it to him for about a week now and he loves it not only that it seems like he is happier, full of even more energy and less gassy which is a win we didn't know we needed. I was a little iffy on the price but the ingredients and its benefits to my pup are definitely worth it!

Happy pup, happy parents.

We received this product complementary for testing purposes and so glad we did. It is very well though out product the ingredients are very simple whole food based. The packaging is clearly labeled and seems like a very quality product. Our pup is transitioning from the the puppy food we were recommended from the breeder we wanted to natural product this will be a great option, she really enjoyed it the kibbles are a good size.

Picky eater approved!

My dog is the pickiest eater in the world and he absolutely gobbled this food up. The ingredients seem very wholesome and natural as well, so kudos to that. The only reason I am leaving 4 stars instead of 5 is the fiber content- my dog’s current food provides 11% fiber while this food only provides 3%. For such a high quality and pricey food, I would like to see more fiber content which I have found is crucial in my dog’s diet.

My dog LOVES this food!!

I was a little hesitant to give this to my dog since she is so picky, but she ate ll of this!! She absolutely loved Pristine, and licked her bowl clean every time.. Usually, she picks at her food throughout the day, but she ate this all in one sitting!! Definitely getting her a bag or two after this one is all gone!

Dog food for review

As soon as I received this free bag if dog food to try and review I opened it. My dog thought it was a treat. I continued to feed it to her as a treat and she kept sitting for it like a treat. My son put down her old food for her and at first she ate it but then she came back to me for her "treat". I would say she liked it.
