Our dog, a seven-month old Golden, seems to have taken a liking to cedar
as a snack, and is gnawing on new boards already. As a younger pup, she
gnawed on some chair rungs and the like, but nothing serious. Now I'm
concerned, not just about the expense of replacing things again soon, but
about the health of the dog. This is freshly painted wood, primed with
stain and finished with latex.

It can't be good for her, yet keeping her totally away from the house is
out of the question.

Fortunately, latex paint is not poisonous. Buy a good book on dong behavior
or take a course in dog handling. Chewing can be stopped. Talk to your vet
for some advice.
