My dog chewed a rubber tree leaf last night, it has been about 24 hours, I just found out.

He wanted to be outside eating grass in the middle of the night.
He ate breakfast this morning with some coaxing, then threw up.
He won't eat dinner, but is drinking water.

His nose is cool and wet, paws and ears are cool.

What do I do?

Sorry, I just noticed this post. I hope all is well ... I ANY case were a pet has eaten, chewed or swallowed something, it is always best to Phone you Vet ASAP ...
