Help, help, help, help, HELP!!!! (My dog is really sick =(()

:cry: Okay, I need help...
Symptoms:
Vomiting(sort of foamy, has a yellow tinge to it) ,
Shivering uncontrollably,
It started out as coughing,
lethargic,
loss of appetite.

Okay, now I can explain...
A night ago, my dog, Pete, started coughing. He would do it every one or two minutes and stop for like, five seconds and start again. Anyways, he went another whole day doing this(I think, I was at school). And I come back tonight and he's vomiting up this foamy stuff. It kind of yellow. Hes also shivering uncontrollaby, is lethargic, doesn't want to eat or drink, and whimpers a little.
He's about 5 yrs old, male, a small dog that is a lot of breeds mixed together, and I can't name some...lets see, Poodle, pekenese..those are about the two main ones. He's seemed healthy enough the past few days, but now...you know.
Can anyone help me? :? :cry:

 

Oh another thing...we have another younger dog, a puppy really. Don't know if that has anything to do with it...

 

I just thought I'd say that hes a little more peaceful. Half asleep, i think. I'm still concerned thought! please!

 

take both of them to a vet, now.

 

I agree with Kyles both dogs will need to be checked over by the vet then if its anything that needs treatment the vet will give him antibiotics or anything else they need.

Please keep us informed..
