We raise labradoodles in our home. We potty train all of out litters so that our families can use puppy play pens with potty boxes to help bridge the gap until the pups are old enough to be reliably house trained. Its really helpful for our families to have a place for puppy with a potty box in the house, when they are too busy to watch closely and get them outside to go potty. An 8-9 week old puppy sometimes has to “go” as often as every 20 minutes! It also means that they can have them in their play pen at night with the potty box, so that they get a good night’s sleep each night and puppy doesn’t get trained to wake them up at night to go out to potty. We want our families well-rested, so they can be good and patient puppy parents all day. In my experience this type of potty box works the best. The puppies get in and out easily, seem to have fewer accidents outside the box than with other boxes I have tried, and they are easy to clean. I bought one years ago at a pet store and couldn’t find them again until I recently found your website. I immediately stocked up. I love the variety of colors you offer! We like our puppy pens to be colorful & fun.
