Yeesh, not good. You need to get some more liquids in her and stop the runs. You said she was infested with fleas? That might be why. They could very well have almost sucked her dry. I've seen that happen beforeyes I was thinking if they are in her digestive track maybe it would flush them out they are not like hook worms that hold on I dont think.
DH is sure they tried to reenter her bum after being flushed out to begin with.
I also am thinking the vet will want to do a blood transfusion. no blood in or around wound white gums and tongue.![]()
