Honey, one thing I wanted to say to you was anytime you make an appointment at your vet but then your pup worsens, call them AGAIN and tell them you need an emergency appointment TODAY!!! All docs keeps some time aside for this, and don't you feel bad about making them use it!!
I sure hope Maddie is feeling better. Her symptoms did not sound good, and I sure was afraid for you, my friend!
Keep us in touch.
