Our Yorkie is 6 mos. old and weighs about 8 pounds and is currently trained to use wee-wee pads. He was doing very well with this method of training and it was working well for us since we both work and the dog is home alone for at least 10 hrs each week day. We have a "play yard" (i.e. plan pen area) in our kitchen which has his crate with a soft bed inside, his wee-wee pad is in the other corner, and I also keep fresh water in there.
Recently, though, the dog has been regressing. He's urinating on the wee-wee pad as always, but pooping on it sporadically (some on and some off). Also, he's been shredding the wee-wee pad when unsupervised. I believe that the wee-wee pad method was good when he was younger since we cannot be home to let him go outside every couple of hours. But, I've realized that we've taught him not to hold it and I'm concerned about this for the long run.
I would like to start teaching him to go outside; now that he's older I think he should be able to hold it longer when we are at work. Although, I read that dogs can only "hold it" for as long as their age (i.e. 4 hours for 4 mos old, etc...) I'm not sure if I wait until he's
10 months old I may not be able to re-train him to go outside.I'm confused and would like to do what's best...What is the best method to use to start training him to go outside now that he already uses the wee-wee pad and what should my expectations be as to how long he can actually "hold it"?

At least ten hours a day ?

The best thing you can do is to get someone to look after your pup in the day or to have someone to call in at lunch time to let him out in the yard and play with him.
I expect your puppy is shredding the pad is lonely and bored and you cannot expect to house train him in circumstances like this. Alison
Consider moving the wee-pad into a dog style litter box, then starting to add small litter to it.
From friends and students using a dog litter box, I understand that they make the transition to outside easily. And because they can sort of cover the feces, some dogs really prefer the litter.

But, yes, having someone come in during the day to take him out to potty and for a short romp will help a great deal.
