TAILS deliver my complete dog food every month - no lugging huge bags from shop to car and car to kitchen! My dog Larry really enjoys his TAILS special mix which is made especially for him by blending specific quantities of different kibble to produce a complete food which suits him ideally. A plastic measure is included which can be altered to accomodate different food measures. The pack contains information about your dogs blend of food and suggests a suitable amount to feed daily. My dog was very overweight when I started using TAILS, now he is just right. I always get an email when TAILS are due to prepare Larrys food and if for example I've been away and he has been in kennels, I can delay the delivery by any amount of time which suits me. The box is delivered by courier and I can even re-use the food bags as they are just right for containing my recycling and three side by side fit perfectly into my recycling box - nice and tidy for the waste collectors! So it's all good and I am very happy with every aspect of my dealings with TAILS. I really can recommend them as a supplier with whom I am very happy.
