Getting 'fixed'

Lily is at the veterinary office today getting spayed.  I know it is a very routine procedure, but I always worry anyway.  She will be just fine, but I'm a momma and I worry about my kids and pets all the time.

She is such a puppy ... full of energy!  How will I ever keep her mellow and calm to let herself heal this next week or two?  It will be a fun task!
