My 9yr old chihuahua her sugar keeps spiking. I need to know asap if you can tell me how to get her sugar down if she won't eat. I am afraid we are going to have to have her put down because she is giving up she won't eat or drink now. So help.

Please this is urgent how do u get a dogs sugar down that is really high if they won't eat so u can give them insulin?

Have you contacted your vet?
I am pretty sure the only way would be with insulin. Is the problem that she needs to eat in order to give her the insulin? Is she drinking? Have you ried chicken boulion in the water? Or making ice cubes with chicken stock? It has a lot od salt in it, so you can make your own. You can try pedialyte to keep her hydrated as well.
