[Nikko's_human]

I was browsing through the Foster & Smith catalogue and saw a little red fire hydrant for male dogs. Apparently this little hydrant is scented to attract male dogs to pee on it. I was considering buying one to try for Nikko, who has been driving me crazy with his marking indoors. Does anyone have experience with this little hydrant indoors? I was thinking of getting it and placing it on a wee wee pad. Should I get it?
