I know that barking is an issue with pyrs, and we don't want to stop it entirely, of course, but we would like to lessen it a bit at bad times--like the middle of the night! Any thoughts about how we might accomplish this with our GP? Has anyone had any luck with the high-frequency sound devices like Bark Buddy for example? I do NOT want to go the shock collar route. Any ideas that have helped others? Thanks in advance.
