  • I Highly recommend this Food!!

    By on

    My German Shepherd puppy loves this food. She's 4 months old and she maintains high energy ALL day. And this food fits the bill. I was feeding her a different brand when I first got her which was another very high quality dog food and she just didn't do well with it. My Vet had this ( and he also has a all Black German Shepherd ) he recommended this product to me. He also told me I could get it cheaper on Chewy . His office charges $75 so I save quite a bit by getting it from Chewy. Gotta love Chewy!!

  • Change from Eukanuba Large Breed

    By on

    Izzy my 9 month Rhodesian did not particularly care for Eukanuba. She would never rush to the bowel to eat. The vet recommended the prescription large breed brand from Royal Canine and she "wolfs" it down. Most importantly she is not having any digestive issues and the end result is much more "solid". Sorry for the dog like puns. :)
