Hi Mark,
It's nice to hear from you. I'm sorry you have problems with your neighbours. I'm writing to give you some advice.
If I were you, I would go to your neighbours and discuss the problem. You could recommend them buying anti-barking collar . Such collars prevent dogs from constant barking. Luckily, they do not cause any harm to dogs. These collars sent vibrations to dogs' vocal chords and dogs don't bark so loudly.
I hope that I helped you in some way. Write back soon and tell me if my advice was helpful.
Good luck,
Yours,
XYZ
