Thanks for the thoughts you guys. she's gone now My Dad was at the vet for 3 hours hoping something would change and she just kept getting worse, we are all very sad but my parents and I thought the best decision would be to put her down, she's been sick for a while and was in obvious pain today. She could hardly breathe and was gasping for air. There was nothing more we could do Echo was a great all around dog, she was always finding ways to make us laugh or smile, she loved everybody and I just can't believe she's gone.....
Thanks again everyone for all your support, you guys are great! I don't really even know what else to say except what I've written above...
