We also have a 13yo lab that's diabetic for about 6 years now, went blind, got majorly depressed and wouldn't do anything, but Mrs. Whiskers took her to the canine opthalmologist without me knowing it and had her eyes fixed. When she could see agin she was like a new dog. She howls for joy every time she goes to the eye doctor for a checkup. The regular vet says Raven is the oldest diabetic large dog they have ever had in their practice, must be from the good care my wife gives her. Deb did a lot of research on canine diabetes, and came up with a feeding/insulin plan that works fantastic for our dog. I asked her to add her process:
This is Deb, I feed Raven, a 75 lb. Lab, Wellness Core reduced fat grain free dry dog food, and a can of Merrick grain free. I can't say its going to be any cheaper but she gets 1 cup of dry and 1 can of Merrick 2x a day, along with 2 shots of insulin. I hope you're getting your insulin from Walmart. $25. I also give her Cranberry dmannose chewables, great for urinary problems diabetics typically get. And methyl b12 that I get as a raspberry flavored liquid that I put a dropperful on her food. Grain free treats, bites of chicken, egg, beef is great. Timing the insulin with the meal is needed,.about 20 minutes to 30 later and you can do your own blood tests with a glucometer to see how your dog is doing. Healthy dogs will run like humans under 100... my dog typically runs 200 to 250 but thats ok... if i get much under 200.. she starts dipping to low... if you want further info.. let my hubby know.
