The neighbours two very large dogs bark continually the entire time the owners (recently moved in with the two "rescue dogs") are away at work...as soon as the owners return home..blissful silence. My daughter in law told me about the Dog House..like a Bird house..and sent me the link..i ordered and paid the extra for immediate delivery..the parcel arrived..i went direct to my Daughters residence (where the dogs are next door)..opened the parcel, popped the battery in, and turned the dial.... "The dogs were barking (and had been since early morning) and there was not a sound after the dial was turned...bliss!!! Now, the only sound you hear is if a vehicle or dog walker approaches, there is sometimes a single bark..then silence. Congratulations!!! Incidentally, my brother is ordering. My sister is ordering. and another friend is awaiting my email to order as I type.
