My Woody Pet experience is not with the indoor potty, but as an outdoor bedding for the puppy play pen.
After seeing a photo of a Wonderful puppy pen, with handsome pellets for footing, and reading the breeder's strongly flattering review of the footing, I bedded my puppy play pen in Woody Pet.
The pellets were lovely, and really do make it easy to maintain a fresh smelling yard. One caveat is to consider the generation/coat types of your dogs.
The Woody Pet is designed to quickly disintegrate into sawdust, which works very well for absorbancy, but dessicated Deva's coat... sawdust worked down to the skin, and a real matting problem with the ultra-dry coat. Maybe it works better with earlier generation dogs. Or in a yard that doesn't allow Mom.
The potty box idea sounds good... I'll be trying that one with my next litter. Thanks, Diane, for that bit of advice, and for suggesting the nuggets instead of chips, which were too fine.
Nice to hear from you, Diane, though it's odd to hear you referring to breeding in the past tense! It seems like yesterday that you and Jac were mentoring me through my first whelping! How's retirement treating you?
