I currently have two mini Dachshunds. Both are rescues; my male is six years old, and my female is five years old, and I have had them since they were puppies. Last winter my male started dropping weight, and fast. I went to my local pet food store and asked them for advice, did some research online and ended up switching him to a “high quality” puppy food and adding extra protein into his diet. Neither worked, and my little guy kept shedding daily to a point where his body score was emaciated. We had our vet do blood work, urine and stool sample analyses, thyroid tests, x-rays and an ultrasound. Everything came back NORMAL! My vet and I were stumped; so he insisted on trying Royal Canin Gastrointestinal High Energy Formula. I was hesitant at first because of all the negative things people had said about “vet food” and its ingredients, but I trusted my vet and did it. Six weeks later, my dog is in the best shape he has ever been in! His condition is perfect, his coat is gleaming, his energy is great, and his eyes are bright and clear. I am speechless. I was so impressed with this food, I switched my female to it, and noticed an improvement in her body condition and coat as well! This food is the real deal, and this food saved my dog's life. If you are having any hesitation, just do it – you won’t regret it. I will stand by this food for the rest of my life. Thanks Royal Canin!
