My dog always pee on a pad or outside she is 10 weeks old , but all of a sudden she started to pee on the floor what happened ? Also she only pees on her pad never poops on it why does she do that ?

How often do you change the pads? I read that a dog MAY choose to avoid a pad that already as been used.

The poop part? I have no idea. Hopefully someone else does.

I'm going to copy and paste a response from another thread. I think you may find it helpful.

Puppy pads are very confusing to dogs and puppies. You are allowing him to pee in the house, and on top of something, he can't differentiate between a pee pad and a piece of carpet or anywhere else in the house. When pee pads are used the puppy never really understands why it is okay to eliminate inside sometimes, but not always. Why can it pee on this piece of cloth, but not that one? Why pee here, but not there?

Truthfully unless you want a dog to eliminate indoors all the time, they do not work and should not be used with pups older than eight weeks of age.

The best way to train a puppy for house training is the crate method. The crate is not used as a punishment, but rather as a den. The puppy does not want to mess in its den so is taken outside several times a day. As it gets older it can hold its bladder and bowls longer and longer (also better food means less poop).

The only time I would train a dog to use pads is if they are unable to go outside, whether it be due to inability to walk or living in an apartment.
If you have access to an outside area where they can toilet that is the easiest and least confusing place for the dog to go.

Is there any particular reason you want to train your pup to go on the pads?

Yes. I am unable to go out all the time. I am 71 years old and prefer that she poops in the house on a pad. HELP.

What is your question? How to train your dog to use a pad? Something else?

Next best thing to having a dog go outside... and they don't get confused between potty pads, carpet and newspapers. These potty patches have high ratings and from people who use them, they claim that they really work!
