We used RC Puppy 33 I believe it was for quite some time. I guess I just never really paid attention to it enough to tell a difference in smell once we changed to Solid Gold (think that was the name of it, lol, that was 2 brands ago) Koda & Kammie both go potty outside except for the occassonal accident when were gone more than a couple of hours.
But I am interested to see if you can tell a difference. Keep us posted on how it goes for you or Chewie I should say, lol!
Good luck
