Pomeranian throwing up, foaming at mouth, and not very active?

He normally is running and playing and we went out of town for a day came back and he was just laying around not moving much and foaming at the mouth and then he would throw up but he only foams when he throws up.
Poms are prone to epilepsy , hypoglycemia. and are very easily stressed. You did not mention who was responsible for caring for the dog in your absence. If he is not moving much, he likely was not fed on the routine that he was supposed to be fed and may be going into a state of shock from lack of food. You were only away for a day, but if no one checked on the dog and he was just left with a bowl of food, he likely did not eat and is going into shock.

The symptoms you describe are not of canine rabies, but possibly seizure. I would definitely involve a veterinarian if you are not able to get the dog to eat or after having eaten, you see no improvement within a few hours.

You also do not mention where you live, but while rabies exists in the US in wildlife and feral cats, there have been no confirmed cases of canine rabies throughtout most of the US for nearly 20 years due to the effectiveness of the rabies vaccination program for dogs.
Looks like he may have picked up something bad while you were away. He may have been poisoned, but it also could be Parvo. With such a tiny dog I would not delay getting him help.

Good luck to you both.
That's not a good sign. Take him to the vet immediately. He may have caught Rabies. He also may have eaten something he shouldn't have like kitchen cleaner. I hope he gets better.
Your puppy is acting that bad and you ask us? Go see the vet !!!

At least take the temperature, if it's high , pay the emergency bill and go see the vet.

It's hard to say without seeing the pup, but if this was a child would you hesitate?
Sounds like a reaction from eating grass. Eating grass will cause all of that. I would get the dog to a vet as soon as you can but in the mean time:
1 - limit the amount of water the dog drinks (dogs when sick will drink till they throw up and then they become more dehydrated)
2 - keep your dog in doors
3 - note down anything your dog could have gotten into (check the back yard, garage, and house)
He could be rabid...or he may have swallowed a fly. He should be taken to a veterinary clinic as soon as possible to determine the cause for the behavior changes and "foaming". Use care in the transport of the animal...humans get rabies, too. The treatment is most unpleasant...

Rabies (Latin, rabies, "madness, rage, fury") is a viral zoonotic disease that causes acute encephalitis (inflammation of the brain) in mammals. In non-vaccinated humans, rabies is invariably fatal after neurological symptoms have developed, but prompt post-exposure vaccination may prevent the virus from progressing. Only six humans are known to have survived rabies after the onset of symptoms. There is only one known case of a person surviving rabies without treatment.

Rabies, or Hydrophobia, is an almost invariably fatal disease which can be transmitted to dogs or humans by the bite of an infected mammal, possibly a dog's, cat's, raccoon's, or bat's. Although rodents and similar small mammals can be infected with the disease artificially, they are generally not found infected in the wild; the current hypothesis is that they are not likely to survive any attack that would infect them. Animals with rabies suffer deterioration of the brain and tend to behave bizarrely and often aggressively, increasing the chances that they will bite another animal or a person and transmit the disease. Areas that are rabies-free, (usually islands) such as Britain, Ireland, Australia, and the American state of Hawaii have strict quarantine laws to keep their territories rabies-free. These require long periods of isolation and observation of imported animals, which makes them unattractive places to move with a pet unless the pet is quite young. Areas that are not rabies-free usually require that dogs (and often cats) be vaccinated against rabies. A person or dog bitten by an unknown dog (or other animal) should always be treated without waiting for symptoms, given the potentially fatal consequences of a rabid biter: there has been only one case of someone surviving rabies when treatment was not begun until after symptoms appeared. The biter should be apprehended if possible, as only autopsy of the brain can determine if it was rabid. This should be a great incentive to dog-owners to vaccinate their dogs even if they feel the risk of their dog contracting rabies is low, since vaccination will eliminate the need for their dog to be euthanized and examined in this fashion should it bite anyone or be suspected of biting anyone. This applies to dogs that are showing neurological signs at the time of the bite. Unvaccinated healthy dogs need to be confined for ten days from the time of the bite (at home or at a veterinarian depending on state law). If the dog is not showing signs of rabies at the end of ten days, then the bitten person could not have been exposed to rabies. Dogs and cats do not have the rabies virus in their saliva until a few days prior to showing symptoms. Ten day confinement does not apply to other species. A dog or cat bitten by a wild animal in an area known to have rabies should be confined for six months, because it can take that long for symptoms to start.
Where was he while you were gone? Could he have gotten into something poisonous?

Get out of your chair, turn off your computer, and go to the vet.

There are many people on this site who know a lot about dogs and give wonderful, thoughtful and intelligent answers, but none of those people can see your dog through cyberspace. We can't possibly know what is wrong with the little guy. A trained professional who is in the same room with your dog can help you. A bunch of strangers all around the world giving you advice is probably only going to get you, and your dog, in trouble.
It could be an allergic reaction to something he got into. My puppy did that a couple weeks ago. I took him to the emergency vet and we came to the conclusion he got stung by a bee and he is allergic! You should take him to the vet asap. He's probably not feeling so hot right now. You want to take it seriously.
