A barking dog as "home protection" is undeniably one additional measure. Contrary to Polly Dillard's comment (Letters, Sept. 10) it has been suggested endlessly.
As an animal lover, I second the advice to choose a dog that desperately needs a home, from any pound or city shelter.
However, I want to underline the statement that the dog should be in the house at night.
Aside from the security of the home--aside from the comfort and well-being of the animal--too many inconsiderate dog owners let their pets disturb the sleep of their neighbors with endless and useless barking.
An outside dog barks at every moving thing, from car to a squirrel, and more often, from boredom, discomfort and loneliness. To be of any use at all the dog must be in the house.
