Please help me, I don't know what to do. He is small 2 -lbs and he ate at least 1 earplug. How I know is he threw 2 halfs up and I caught one but he ate second half again. He may have ate 2 earplugs total, can't find the 2nd one.

Call your vet right away.

I am sure you puppy will be okay, but you really should call the vet immediately.

No reason to panic. If it went down, back up, and down again, likely it is not a choking hazard. It could still cause an intestinal blockage, but they don't require immediate attention. Certainly if he starts vomiting and diarrhea, call the vet. You could administer a little peroxide, maybe a teaspoon. That should bring up everything in his stomach. Perhaps do so outside and not in fenced fenced area you have. That way you can quickly remove him from the area before he gulps anything down.
