I just wanted to wish you good luck with the U of Tenn and potential surgery. Hopefully everything will go through with the Care credit card. Are there any family members who can loan you money to pay for the surgery? After you pay them back you can put some money away monthly in case this ever happens again. It really is hard to anticipate the cost of owning a dog on top of all the premium quality items we buy and provide but unfortunately it's a reality.
Get well soon Gus
