My Dog Is Acting Sick, Shaking, Won't Eat, Acting Really Tired?

Loss of appetite and no drinking in you dog can be due to pain, that is why he is shaking. Pain is major cause of shaking in dogs. Common causes of shaking in dogs are

1. Pain
2. Skin parasites
3. Fleas
4. Exposure to heat and cold
5. Ear infections
6. Nervousness

Some tests are needed along with physical examination to diagnose proper cause of your dog's problem. You can not do anything at home to diagnose. In my opinion,  take your dog to vet who has also facilities to diagnose accurately and he is competent enough to treat your dog.

Last night my dog throw up her food and now today she will not eat nor drink water she just lye around and shiver like she is cold she also yawn a lot and when I try to open her mouth she shakes please help me I'm worried about my sweet girl

He was perfectly fine then did not see her for a whole day then the following morning found her under the storage building, really weak, and wont eat and wont move around, she just wants to lay there. What do I do?

Please take your dog to a vet.  It may be nothing, it may be something serious.  
Especially given the fact that he won't eat, there may be other issues.  
Our dog had similar symptoms as well - shivering, not eating, moving around stiffly, sleeping more than normal, drooling excessively and not wanting to get up - this all happened over the course of 1 day.  We waited overnight, hoping whatever it was would pass, then took him to the vet the next day.  Our normal vet referred us to an emergency specialist as they suspected canine meningitis.  We took him to the specialist and 2 1/2 days and $3000 later, our 8 month old pup died from canine meningitis / gme.  In my opinion, it would be worth taking your pup to see a vet ASAP...

My dog had the same symptoms. Your dog is in pain. First of all, examine your dog: Push on belly, neck, throat (that's where my dog's pain happened to be), around eyes and ears, different spots inside the mouth. If any specific area hurts, it might be an abcess. If you think he's gotten into something poisonous (if so, he might also have vomitting and diarhea) - give him a tsp of hydrogen peroxide per lb of weight, that will make him throw up. Check for fever. Even slight fever means that there's an infection somewhere. He needs anti-inflammatory: A shot of Dexamethazone (that's what they give in emergency clinics), or get some children's liquid Tylenol or Acetaminophen (make sure it's NOT ibuprofen or aspinin!!!) and give a little to your dog. If there's an infection, the dog needs antibiotics also: Cephalexin every 8 hours (for a dog about 45 lbs). Keep the dog hydrated (you can force-feed him some Pedialite if he won't drink water).Reduce activity. But still take your dog to the vet ASAP. The exam costs vary from $65 to $90, and medications can be another $30 - $50. I think it's worth it to save your dog.

My dog can't keep her food down and vomits continually
and will eat grass forever if we let her.  She is a ten year old lab mix dry nose

Shivering in dogs can be due some normal conditions like cold or when dog is wet. Shivering other than these conditions can be due to some problems like when dog is nervous, due to weak muscles, arthritis, pain, fever, internal parasites, joint stiffness, autoimmune disease, bowel problems and infectious disease.
These are few possible reasons. Final diagnosis will be made by your vet after physical examination and different investigation. So, take your dog to vet.  

I am not a vet -- so this may or may not be the answer -- but my dog displayed the same symptoms and it was pancreatitis due to hypothyroidism.  I was lucky she lived through it but barely.  Good Luck  

We have taken my do to the vet. He did have a stomach bacteria and it cleared up, they did a stomach exray and checked his teeth and for worms . He will not eat dog food, sometimes he will eat boiled hamburger or hot dogs. He goes a day with out eating anything sleeps a lot. He is 7 yr old blue tick coon dog. Help

If it does it 24-7 than it is really sick and could die you need to take it to the vet like right now

This is due to bad food and you are not giving right food to your dog. Your dog may not like the food you are giving him so change the dog food. Try some boiled chicken meet and milk. She may be feeling lazy due to weakness. So giving your dog right food can make difference. She is sick due to loss of energy and shaking as well so you can give her appropriate dog food. This can solve digestive problem in your dog so you can take your dog to good vet. Some dog show same feelings during separation anxiety so there is no perfect solution for dog separation anxiety other than taking your dog outside and playing with your dog. This can take your dog back to normal position. However taking your dog outside can really help her to feel better.

Well, My friend told me if he is shivering, he is being stressed out. Like if you drop him on accident, or throw him like on a bed of on the floor, if he falls, he's being stressed out. But he might be cold. I have a small dog, and I always though he was cold so I put him under the blanket and he was just fine. You might want to take your dog to the vet to see what is wrong.

If your dog is shaking he may have a nervous condition take him to the vet to rule this out.and if you have him check out and he's still doing the same thing then your dog may see something with his eyes that you don't see.
