My boxers will bark only when they feel the need.

For example,
The laundry trundler must always be barked at!( Biting of its wheels , mandatory!)
The Vaccum cleaner was invented to be barked at!
( extra points for attacking it!!!!!)
The postie must definately be barked at! Especially when she comes in a different vehicle!( lunging at the steel gates , optional!)
Anyone seen walking around at night , with a towel on their head or rain coat on , definately warrants a bark!(Merit points for deep throated growls!)
All visitors recieve the "boxer bark welcome" ( kidney beaning and bouncing off the guests standard proceedure)
And the boxers favourite?
The orchardists motor bike!
This is accompanied by the boxer hoon!
Hooning is when 5 irate boxers pound madly around the fence line, barking wildly, in a pathetic attempt to catch the motor bike racing around the orchard!
Nah! Boxers dont bark much! :p
