I have a ugodog that I purchased for my 12 week old shih-tzu puppy after weeks of less than positive experiences with newspapers, disastrous experiences with Purinas Second Nature puppy litter box and expensive pads. Mi-Joo is now 9 months old and has been successively using the UgoDog since the second day. I had great hopes for the puppy litter box but she spent far more time chewing on the side of the box and even the litter than I had ever anticipated. I promptly traded the expensive litter for newspaper but had the same misfortune. I then bought pads which seemed to work but still had glitches.
The entrance to the litter box was simply too high for a 5 pound puppy to get into on her own when she was racing against time. Plus, I would then be stuck cleaning soaking wet foot pads and legs. Disgusting. I have a beautiful yard that I have no intention of turning into a giant toilet so I knew I had to do something. Enter the UgoDog.
When Mi-Joo needs to go she simply walks over to the box, circles a couple of times, does her business, waits 2 seconds while I wipe her "whats-it" and then races me to the toilet to flush the tissue. Simple, clean, easy. No more wet paws or legs. The grate is fantastic for catching urine. For poop, well, that can be a nasty little mess. But I figured out a while ago that when she poops all I need to do is place a piece of kleenex down below her rear-end. Then when she is done I fold it and flush it and we're all done. It's all good!
For clean up I spray the entire thing down with a vinegar spray and wash with hot water. If I am in a real hurry I will cheat with Dow Scrubbing bubbles spray but either way, as long as you don't let poop get directly on it, it is super easy to clean.
Cons: 1) The sides are too low for a young pup and you will have to help them aim. 2) The box is both too shallow and too narrow (in width) to successfully use newspaper - besides then you have to pick up sopping wet newspaper, eeewwww. 3) The grates can allow poop to fall in and create a nasty cleaning event. 4) The box is simply not sized to fit any of the pee pads on the market so you will have to do a little creative fitting of the pads yourself... 5) $50 (including shipping) really does seem like a high price to me. I don't see why this product could not be sold for $20-$25 instead.
Pros: 1) The grate system allows for a completely non-messy urination experience, no dripping! 2) The grates are soft and easy on a puppy's sensitive feet, thereby encouraging her to get with the program. 3) The box itself is rather tough and stands up to even vigorous chewers (like mine). 4) The whole system is fairly light weight and super easy to take and go. You can move it to different rooms, even take it when you travel. 5) The system cleans easily. 6) UgoDog prevents even newspaper from leaking onto your floors/carpets. 7) The double grate system allows for quick disposal of even diarrhea (provided you place kleenex down first). 8) Fairly unobtrusive as well, no unsightly giant box to dominate whatever room it is in. Also, the fact that it is so easy to move allows you to easily train your pet to eventually go in the room of your choosing.
Bottom line, this is a great product and although I have a couple of tweaks I would wish for I still think this is the best thing on the market. Get it, you won't be disappointed.
BTW, Yes, I still use pads (clean go puppy pads are your best bet value wise, btw) but now I use less than half the number of pads I had before.
