If your vet has diagnosed your pet with Diabetes Mellitus then we can help you by providing your prescription insulin and needles and syringes or pens. We can also provide test kits to check your pet's glucose levels. You will need your vet to teach you how to do this. 
There are specific veterinary diets to help manage diabetes too which even out blood glucose levels and often include extra fibre in the canine diets. They are often lower in carbohydrate particularly in the feline diets.
