HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bailey! He is adorable! Regular insulin is short acting and needs to be given every 6 hours which is not feasible at home. The only time I have prescribed regular insulin is for diabetic cats who have acromegaly. My suggestions are to discuss with your Veterinarians over the phone how to gradually increase Bailey's insulin dose. You can be taught, by purchasing a glucometer (made for animals not people), how to measure his blood sugars at home. The glucometer itself is initially expensive but it may save you in the long run. Also using Keto-diaticks to measure ketones and glucose in his urine. That way you can do blood sugar curves at home and report to your Vet. My other thought, is that Bailey may need a different insulin. Overall we may just have to wait for his pancreatitis to resolve. Pancreatitis can make diabetes hard to regulate as can Cushings. If Cushings disease is suspected he may need to be tested for it and treatment started to help regulate his diabetes. Sadly cataracts are almost inevitable in our canine diabetics. Maybe when you recoup your costs you can consider having the cataracts removed. I am sorry you and Bailey are struggling and I wish you both the best!
