Someone I know
has a neighbor who's dog's are normally let out around 8 in the morning and taken in at night. And from 8 am until they go in the one dog lets out a bark about every 4 1/2 seconds...it CAN BE some kind of torture...
However, ALL the dogs in my, er, HER neighborhood bark from time to time, especially Miss Ginger, so "my friend" doesn't feel she should complain...but all day, everyday, can get to be a little ruff.
BTW, I thoroughly enjoyed your post, you had me laughing outloud! Sounds to me like your big guy's just being a dog. There's a big difference in my book between occasional barking and nuisance barking! Let us know how it works out.
