what happened? what was the surgery for? Im soooooo glade to hear that she is alright.
I'm a little protective when it comes to beagles can I ask you if she had her parvo shot as a puppy? she probably did if she was at the vets and had sergurey. If not you should take her into get one, beagle puppies are very prone to the parvo virus.
I hope you enjoy your beagle she sounds like a walking miracle.
