Should the time come when you have to help Sydney to the Bridge, please know that it's painless and quick and you can be right there w/her, holding her, soothing her and giving her the love that she has given you. It's the last act of kindness that we can do for our beloved pets. Unfortunately, I've had to do it several times through the years w/both dogs and cats and it isn't easy but then, it isn't about us, it's about helping our fur friend out of pain and suffering. God bless you for all that you're doing and have done for Sydney but never give up hope. I know that it's frustrating w/all that you're experiencing but things just may turn around. Know that we're all here for you, no matter what course you decide to take. (((HUGS)))
