What is wrong with a dog who is shivering vomiting has a temperature is tired and doesn't want to go outside and hasn't gone to the bathroom all day?

this could have something to do with the thyroids so check with your vet! my dog shivers a lot but has fine bowels and everything... he is just sensitive to heat and cold. Take your dog to the vet immediately. The vomiting could indicate many illnesses, obstructions, poisoning, etc. So not wait. If this condition persists for any length of time, the dog is suffering from having an owner who doesn't take it to the vet. Such symptoms could be caused by a number of things, and some of them could prove fatal. Take the poor thing to the vet. I know it's expensive, but some things you just can't take care of yourself.
