My dear, sweet Dixie spent the weekend throwing up and on Sunday night, she vomited blood and stomach bile. I looked at my husband and said, "This is bad. I think this is the end now." She was wiped out all weekend from being sick. It wasn't so much the amount as it was the effort, I think.
I had "the talk" with her before I went to bed on Sunday night, and told her everything would be alright and if it was easier for her to go on her own, that I'd understand.
She made it through Sunday night, but on Monday evening, just last night, we had to have her put to sleep.
