soooo tempted to write a smartass answer...but if true, this could be serious - take the dog to a vet asap.
More than likely the lighter will pass without a problem in a day or two. Feed him lots of fiber to get things moving faster.
if it was a zippo lighter , you can send your dog to the factory and they will retrieve the lighter for free :o)
for those taking this question and turning it into a judgment session....F OFF ! get a life.
Offer him a cigar
I'm feeling you.....
What kind of question is this? How old are you and who thought you would be able to take care of and handle having a pet? Do you take care of yourself? In case I wasn't clear, I am not being serious because this surely isn't a serious question?
I would be afraid the lighter would tear the dog's insides....how in the heck did he swallow it? What a crazy dog!! WTH was he thinking?
So what happened? What did you do?
Don't smoke around or expose dog to an open flame.
