Thank you all so, so much...I can't believe the amount of comfort I've found here. It's helped me more than I could put into words.
Kelli's regular vet, the one we just LOVE, called tonight. She was so, so sad and that broke my heart even more. She just adored Kelli.
Kelli would go in and give her kisses (one thing that Kelli loved to do, was kiss toes, lol! If you had your toes out of your shoe or you were barefoot, and she liked/knew you, she was kissing 'em! -- one time, her vet had a broken foot and was in a cast...toes sticking out, the minute that Kelli got into the room she went right for her foot and gave her a quick kiss...we called it a drive by, lol) and she never once snapped at her.
She looked over Kelli's xrays, and she agrees with what the EVH Dr's found. Enlarged heart and enlarged liver. The Dr. called it arrhythmia...something, it was a long name. I don't mean to sound silly about it, but I honestly was crying just hearing how sad she was and I could barely understand. She said there was no fluid around the heart at all, and that is why she was sent home. Because sometimes these situations do clear up on their own. But, she also said that we did everything we could, and these things come on very quickly and there's really nothing that can be done. She was a little disturbed that we were not told until AFTER Kelli passed that she had an enlarged heart and liver (the EVH Dr. didn't tell us when we picked Kelli up, only after she'd already died), she said he could have been more honest with us about the xrays...but she made it a point that we did everything we could.
It still hurts alot, we miss her so much. But, I know she's pain free now and she's happy with all of her new furry friends, and she's seeing Grandpa again. And that makes missing her a little easier. Thank you guys, one more time, for helping me and my family so much through this.
