My Border Collie was diagnosed with diabetes at the age of 10 and was eating Hills WD, which has low fat and low protein, what her vet said was appropriate for diabetics. She was gradually declining, as one does with diabetes, experiencing hair loss, chronic urinary tract infections, and neuropathy. She lost her eyesight due to cataracts, but received lens replacement. During recovery from the surgery she refused to eat the WD, mostly because the medication she was taking made her feel ill, but she never really liked the WD to begin with. After doing some research, I decided to try a no-grain food. I was concerned because her vet really put the fear of "anything but WD" in me, but a different food was better than not eating. She loved the food (I fed her the bison recipe) and immediately began to gain her lost weight and energy. Her blood glucose level became more manageable and I was able to decrease her daily insulin by about 30%. Soon her hair began to grow back and the neuropathy decreased. She had been unable to go up or down the stairs without assistance (she had several bad falls) but soon was navigating those again. She was slow but steady and strong. One other benefit that I can attribute to the grain free diet was the complete cessation of UTIs. The WD gave her soft and copious tools, and the grain free diet eliminated both of those conditions and she no longer contaminated herself when she pooped. Incidentally, I also began feeding my other two dogs, a Border Collie and a lab mix, the same food. The lab mix was previously eating low calorie food to maintain her weight. Although the Blue Buffalo is quite high in fat and protein, she lost weight and is slim and trim in her senior years. Sadly, my diabetic girl passed away from cancer just before her 15th birthday. I am confident that the change to Blue Buffalo gave her more years, and happy ones.
