Power Bone Dog Treats

I have a trouble finding time to brush the teeth of my dogs so I usually buy dental treats.  Have recently bought Power Bone (small) (3 for 65 php).  Upon opening I gave it to Lychee (our maltese) but she didn't like it.  Luckily, our sharpeis' liked it.  It was swallows instantly liked it vanished.=) How about you have you tried this yet?
