You need to give insulin shots if it is required. Apparently your veterinarian thinks the condition is severe enough that insulin is needed. Along with giving insulin I would suggest you try DIA-IONX because it helps to control the symptoms of diabetes and it's therapeutic mineral base helps activate the enzyme systems in the body that help with healing. Some owners have told us it has helped stabilize the blood glucose levels for their pet. After giving DIA-IONX for a while some owners have reported that they have been able to reduce the insulin dosage and some have been able to stop giving it because their pet no longer needed it. However, each patient is unique and has its own set of circumstances. One cannot stop giving insulin until the body no longer needs it. In addition make sure that you offer sufficient water free of chlorine and free of fluoride. A regular exercise schedule is also helpful in moving glucose from the blood and into the muscles which will reduce the blood glucose. It is important that you monitor the blood glucose levels so that you can ask your veterinarian about adjusting the insulin dosage when necessary.
DIA-IONX is easy to give because it is liquid and can easily be added to the food. I like to split the dose and give half with breakfast and half with supper. I would also give MSM, probiotics, and Omega 3,6,9 to support the body of a diabetic.
Please let us know how you progress and if you have any other questions.
