We had the same problem in our village, the Parish Council got involved and helped to sort it, with the Environmental Health people as the owners didn’t bother and many many people complained.
In fact their dog was so bad at being left on its own all day they bought a puppy to keep it company, this resulted in 2 dogs barking all day! In the end one of the owners of the dogs gave up working which sorted out the problem.
Try the note through the door though, but I doubt it will work, we just got a lot of bad language back.
