Oh, AdoreMyDogs, what a horrible experience for you!!! Your story reminded me of the old Disney movie, "Where the Red Fern Grows". Do you remember it? I only saw it once as a child and still remember that one dog lying on the grave of the other one.
I haven't experienced it with a pet, I only know how my daughter and I grieved when our Cocker Spaniel, Kaycee, had to be put to sleep. Honey was too little to realize what was going on. She got so much love from us, she was thrilled.
Glad to hear things are better now.
