Do female dogs go through menopause too?

Ok this might be a weird question & I'm probably thinking that the answer will be no. But I was wondering, do female dogs who haven't been neutered ever stop coming into season? My girl has just come into heat & as you maybe aware, this is messy...I am currently trying to save up to get her neutered as I feel at 5.5 years old, she is getting too old to have a litter of puppies (we have a boy too) so I am hoping she doesn't fall pregnant this time. I guess I'm just asking this more out of curiosity & trying to not look stupid to the world at the same time lol.
