Johnny my dog

I’m raising money for my dog Johnny . He is very sick with ketoacidtosis diabetics and he is blind . He is only 8 years young and he needs a treatment that could potentially save his life . I can’t bear . to put him to sleep which was option number 2. I have had him since he was 5 months and he is like my child . I been in major distress over this and it hurts . So anything will help . For this life saving treatment . Thank you all
