By putting three or four thicknesses of newspaper in one spot, you have taken charge. Another good alternative is to have a friend or neighbor take the dog outside to his spot while you're at work. If you plan to be gone for only a few hours, take the dog outside before you leave. Then put the dog in the crate with a small treat and a couple of toys. If you'll be gone more than two hours, confine the pup in a restricted area as described above.
Older dogs can remain in their crates a little longer.
When you return, immediately take the puppy out to the same spot. Then remove the water bowl. An hour or so before your bedtime, take the pup out for the last time. Put the crate in your bedroom before putting the dog to bed for the night. Then put the puppy into his crate with a toy and a small treat.
