Some great advice here! Question: Is a "litter box" the same thing you'd use for a cat, with cat litter in it? I bought puppy pee pads and thought I'd use those. Which is better long-term?
Tom King uses a litter box like a cat uses and puts Equine Horse Pellets inside the box. His puppies start using the litter box when they're about 4 weeks old. From pictures it looks like Tom has his litter boxes on a screened in porch where his puppies and dog go to use it. His dogs also potty outside, as well as, being indoor housebroken.
Several of us on this forum have indoor house broken our dogs and use Equine Horse Pellets instead of puppy pee pads inside potty trays that have grates on top. The grates keep the paws of the puppies and adult dogs clean when they use it. If you use an open litter box the dogs pick up saw dust and equine pellets on their paws, carrying some of it out of the box onto the floor. It depends on your situation on which method you use.
I've used about everything. Artificial grass, pee pads, Equine Horse Pellets along with four different potty trays. The artificial grass smells, as well as, the pee pads. That why I and others like the Equine Horse Pellets. There is no odor. When the dog pees on the pellets they expand and turn into a clump of saw dust. You, also, don't have to change it out as often as pee pads. I've, also, used Equine Horse Shavings when I couldn't find the pellets.
I keep pee pads handy and sometime use them in a pinch. When I use pee pads, I use them inside potty trays and have never just laid them on the floor. Some people do this. I'm sure my little one would have played with it and torn it up. If you put the pee pad inside the trays, the dogs can't get to it.
There are potty trays such as Richell Trax Mesh Tray, Ugo Dog, Byliss Pets Klean Paws plus others. I have all these and they work, however, Ugo Dog and Byliss Pet's Kean paws work the best with the Horse Equine Pellets.
Here are the links two the trays on Amazon. You have to order direct from UgoDog. It is a larger tray than Byliss. Depends on the size you need. Hope this helps.
