Using Cat Litter for Dogs:

I used this method for potty training my dog, it works great for small dogs.
If you live in an apartment, and have a small dog, a cat litter box may be your solution.
When you notice your dog looking like he needs to use the bathroom, just plop 'im in the litter box.
Or, put him in at regular time intervals, like for a puppy, every half hour to a hour. They like the way the litter feels, a good place to go potty. Now for some verbal training while you are at it. Whenever your dog starts to "go", give your command such as "go potty" or something like that. This will train your dog to go whenever you give the command! Want some more help? Check This Out!

Clumping litter is cool because well, it clumps, making it easier to clean out and makes less waste of good litter, plus you can scoop it out right after he/ she goes so that you can have a fresher-smelling litter box. The disadvantage, however, is that if you have a long-haired dog, it makes really bad mats; if your dog's paws or legs have the slightest bit of moister on them the litter will stick to the hair and will probably mat it. When the litter gets wet, it gets really sticky, that forms the clumping action. I found the mats impossible to comb out so you'll have to cut them.
