Good Bye Catie

Today is one of the saddest days I think i'll ever experience. We have 3 dogs... mine, dasiy, is a yorkie and is like 11. Catie, tylers, is a mini shnauzer (10) and Skye, travis's, mini shnauzer (3)... all are like family... litterally. they slept with us, rode in the car with us, sat on the couch with us... cuddled us when we had a bad day, played with us and gave us sooooo many memories. Catie was put down today... her heart was enlarged and cutting off her treacha and fluid filled her lungs. The last few days she got progressivly worse, so today i was headed home to go say good bye... only thats when i got "the call"... they put her down earlier and didn't want to call me at work... i never got to say good bye. I know alot of people don't understand, and i dont expect them too but i feel like i just lost a sibling, best friend, etc. I have no idea if dogs go to heaven, so im just holding on to that option to sooth myself... AHH its way too hard.
