I am so glad that a vet saw Raggs and could help, and that this might be just another stumble, and I'm hoping nothing more serious.
What a journey Raggs has been on and taken you with, he's such a little trooper.
I have given my dogs apple juice (with no added sugar or high fruxtose corn syrup, as close to organic as you can get), when they have needed fluids. Don't know if that would help over there.
Will be hoping that the little guy turns around soon. ((Higs))
