Our Lab clearly likes this better than the Blue Buffalo she started on (confirmed with a side-by-side bowl comparison ) and its attributes for reducing the odds of hip dysplasia that's all too common in many breeds was the initial deciding factor.Also all of the other attention in the added pre and pro-biotics, Omega's, DHA ( omega-3 fatty acid) etc., is more thorough than the other quality brands she has had, like Wilderness.One reviewer said his dog had diarrhea when starting this brand. Even people can experience thsi when changing their diet-esp to a more healthy one. Another reviewers Veterinarian recommended adding a dollop of Yogurt, which may be a good idea even with the pre+pro-biotic already in the recipe.What we did was mix what she was used to eating with this new food at perhaps a 60/40 (old/new) ratio and she had no transition problems. Her coat looks shiny and better than ever compared to our previous other top band.We also use Tropiclean Fresh Breath oral care water additive (I've no affiliation or interest with any brand of anything except as a customer), and only mention this because it also has Omega 3 (and 6) Omega's, and she gets an egg a day, both of which may be helping her coat shine as well, but we used these with her old brand and her coat certainly did not pop like it does now.To what degree this helps with her coat is impossible to say; it's only a cap full per 16oz and ingredient concentrations are not listed.
