My condolences De. I went thru very similar thing with my 12 year old Brittany Spaniel a couple years ago and had to take her to Vet and have her put to sleep from Cushing's Disease. I sat on the floor with her and talked to her as she grew groggy and fought it..
Yes, it is an emotional and difficult time to lose a close friend like your pup. Few things make me actually cry but having my girl put down was one of them. I hope she forgives me..
I feel for you and hope that the sadness and pain will not last long. Your child was very sick and you did the right thing. Mine was far less ill than yours. I still feel guilt over it and even though I have a newer 2 year old playful 60 pounder I still miss Maggie dearly.
My condolences to you and yours.
