It's been awhile sorry, but I wanted to thank everyone for the great advice. Daisy is better, although I'm not 100%positive why. One of two reasons: a. we switched her from canidae to a different food...I was suspicious of the papaya, but can't be certain. and b. the dogs had been drinking from plastic bowls, which my boss(I work at an animal supply store) had informed me is a haven for bacteria. Since we switched to glass bowls and started changing her food over at the same time I have no idea what worked. But her swelling is down and she's back to normal again(yay!)
