I have never heard of the citronella anti-barking collars before?? Schatzie is not a bad barker at all but our Schnauzer Annabelle is awful,
Maybe if good results come from this I might try it for her?
I used to use a water bottle to spray Annabelle when she barked obsessively but she'd just move to the other room and barked. I got real tired of chasing her around with a spray bottle.
That, and I looked real dumb doing so.
Also, even in public Id have to carry my "spray bottle" around with me and it was a real nuisance.
This citronella collar might be something to research on and am curious to read other member's comments/suggestions about it.
