Chihuahua puppy has lost weight, vomiting, whats wrong

Over the past 3 or 4 days my chihuahua puppy has started throwing up, she wont eat, and she has had a little diarrhea. In this short amount of time she has become VERY thing.I can see her back bone! I called the VET last night and got a machine.no emergency # to call and no emergency vet in the yellow pages.so I cant take her in til Monday.

Does anyone know what would cause this out of the blue? All she is doing is laying around.she usually plays and chews.she hasnt even done that at all.

I just bought her like 6 weeks ago.can someone please tell me what is the matter with her? Gosh, tomorrow cant come fast enough to take her to the Vet!

Thanks everyone!

the loss of weight drastically is dehydration. try getting some unflavored pedialyte from the store and force it down the pup. since it is a chihuaha, i would give it a dropper full every 2-3 hours every hour would not hurt to be honest. I would say parvo, but the virus usually kills within 3 days of the pups first symptoms. It could be worms , worms can cause a virus that will lead to parvo. GET to the vet first thing tomorrow morning if it is not too late, I would call around until you found a vet with an emergency number. Your pup may not survive until tomorrow.

Is it drinking water at all? Is it going to the water bowl and standing in the water and not drinking?? It is running fever and more than likely worms, but can very possibly be the start of parvo and it is CRUCIAL it gets to the vet IMMEDIATELY
