Try some star jasmine (Trachelospermum jasminoides). It will bloom almost non-stop until the end of Summer and may go on for longer dependingly.
Its a vine, but you dont really have to trellis it, it is often used as a ground cover or even shaped into a small hedge.

tj,
Contact the county office where you live.
Tell them you can't stand the smell, and why.
That is not only unpleasant for you to smell, but it
is a health hazard to have all that animal poop rotting
like that close to your residence.
You shouldn't have to live like that.
It is their choice to have the dogs, therefore, they have
to pick up after them.
Then after you lodge a formal complaint, go out and buy whatever plant you want. The jasmine plants are wonderful for you.
And not having that stink all the time will be even better.
Complain,
Squeeky wheel gets the grease.

I read somewhere that in Japan they use Osmanthus fragrance as the typical "bathroom perfume/odor eliminator" because of it's pleasant smell. The end result is lots of Japanese associate Osmanthus with the bathroom! So be warned, combining a nice fragrance and a bad fragrance just makes you gag when you smell the nice fragrance!

Agreed, call your town and report the dog problem. Fragrant plants aren't going to be able to cover up a bad smell for most of the year.
