During the first phase of regulation, you can use urine strips such as Diastix, to monitor your pets glucose level. They can be purchased in most pharmacies, and are inexpensive. Your pharmacist can normally help you find the right product if you are unsure. Once your pet is regulated, and the strips start reading negative, they are no longer an accurate judge of your pet’s condition. Glucose Meters are available which require only a small quantity of blood. You may obtain the blood by using a lancet on the ear or footpad of your pet.
