I got this a year or so ago (many pet stores carry it) because I'm a little too lazy/forgetful to brush my dogs teeth regularly. You're supposed to put the doggy toothpaste on the brush ends and let your dog chew away for 2 minutes -- well the "lazy/forgetful" part of usually leaves this thing with my doodle for about 10 minutes which results bleeding gums (nothing to get scared about though) and lots of dents in the plastic. So I haven't used it in ages.
Not sure it is quite as effective as concerted, regular brushing. If this review section had a thumbs up/down feature...I'd give it a thumb pointing to the southwest.
So back I go to brushing a few times a month (the dog's teeth that is).
I never heard of this. I'm willing to give this a go. I don't know what would be more "lazy " of the two, my failure to brush my dog's teeth or failing to give them the easy brush. Think I'll pick the former. Thanks Adina!
