Ohhhh, I'm sooo sorry that you are all going through this! I'll be praying for a quick, easy surgery & recovery for Miss Sophie. In the meantime, I know that you have the best treatment for her, b/c all those snuggles & tummy rubs will make both of you feel better right now. Big (((hugs)) to you and please give Sophie a "get well soon" kiss on her head from me.
How is Syrus doing on the anti-inflammatories? Is he moving more comfortably, now? Poor pups going through this, but they are blessed to have a mom that's taking such good care of them!
