Most of my dogs have had this illness which causes loss of appetite, vomiting and watery diarrhea. It took Fudge about three weeks to get over it, but some of the others have gotten better much faster. Morgan was sick for about 36 hours and is now fine again.
Sky is in his second week of the illness.
Last week Tess became sick, but was much improved in about four days.
Because of the vomiting and uncontrollable diarrhea, she is getting no nutrition from the small amount of food that I can coax her to eat. Her body had started feeding on itself. She has no fat left and now the muscle is being used to keep her alive. On Tuesday morning when the vet examined her, he said that we're very close to the point of no return. If she loses about two more pounds, her body won't be able to come back from this.
On Tuesday she received an injection for nausea. He said that her intestinal tract is a mess, but she's still a happy dog and suggested I try feeding her liver. Over several hours that day she ate four chicken livers and about 1/4 cup of kibble. The injection worked and she didn't vomit and went for 32 hours without a bout of diarrhea.
The next day she didn't want liver anymore, but did manage to eat about 1/2 cup of kibble with each piece being hand fed. Her stool yesterday was slightly improved.
Today she has eaten almost a cup of kibble and her stool is about the same. Tomorrow morning she'll get another Cerenia injection for nausea and we hope it will get her thru the weekend and allow her to continue eating. We're very close to the line. If she isn't improving by Monday, we'll probably have to say goodbye. As you can imagine, I'm spending every minute trying to coax her to eat and holding my breath waiting to see if it stays inside her.
