Have recently started adding "sprat sprinkles" to my dogs biscuits and have noticed their coat condition improve dramatically. We feed a good quality kibble and try to keep the treats natural and low fat, but the sprat sprinkles (dried sprats and sprat flakes) have been great. In fact we have been tring to keep some weight on our little working girl and this seems to have done the trick. Would highly recommend them. We get them from Mariners Choice, along with the salmon and potato treats. And they are great at customer service. Finally feel we have the right food (millies Wolfheart), the right snacks and two happy, healthy dogs...
