Hi Elaine,


 thank you for your question and sorry to hear that Ruby is so sick. It is hard to know whether you should put her to sleep without seeing her and conducting an examination in person. 

Diabetes Mellitus (DM) is a very complicated condition and its management can be confounded by many other environmental factors as well as other disease. If the diabetes has been well controlled and is suddenly not, then I would suggest there may be another condition occurring now ie Cushings disease. If the diabetes was never well controlled then she may need to spend some time at the vet clinic while they get the dosing and feeding regime correct. 

Dogs with DM often/always develop cataracts due to an accumulation of sorbitol in the lens, which is a by-product of having a high blood glucose level. This can result in reduced vision and possibly blindness and may explain why Ruby is not seeing well.

I think you probably need to chat to your veterinarian about her quality of life and diabetic control before making the decision. I am sure that together you will come to the right decision.

Good luck at this difficult time,




 Anthony and James.
