Healing thoughts and well wishes are being sent your way. It's always hard to decide on surgery; especially after a beloved animal is still recovering from another procedure. Jack's been doing so well for the past year; and in that time he's completely healed and recovered from his leg surgery.
Don't feel bad, Mike, your reasoning for waiting on the surgery was sound. Now Jack is healthier, and better able to withstand the stresses of the hernia surgery.
Good luck; we are pulling for you.

, Jack.
