I have worked in the pet industries for 10 years now and would just like to offer the following advice for people trying new foods for their dog. Every dog is different and will not always react differently to the same foods as any other dog. I work in a store where we only sell higher end dog foods such as wellness, solid gold, nutro, merrick, and all the others. I sell this food every day to people but at home use Pedigree with fantastic results. Please just remember to change your dog slowly to a new food, give it at least 1 month to see changes in skin and coat, and don't be upset just becuse I kind doesn't work for you. Hopefully you have a helpful pet store in your area. If you don't call one for advice. If they won't take the time to talk to you about your problem they shouldn't get your business.
