I think Yorkies are too high energy to crate all day and all night. It's just not healthy to keep them so inactive for so long. They need their movement. If you had a baby, you wouldn't confine it in a crib all day if it's learning to crawl or walk. That would impair the baby's development and I feel like it's the same with a baby dog, in fact, moreso.
With the pee pads, they do tend to smell, and so my husband and I decided to change it daily. It's an expensive proposition if you have a pen lined with them, so you might want to get a "Small Animal Playpen" which has extra panels available to expand it's size. Then put a pee pad in one end and the crate and food at the other.
My other suggestion would be to take a week or so off from work, and use it to train the puppy to use the pad. That way, you could then use the setup above which allows the puppy more movement. Coming home at intervals during the day and giving the puppy some more exercise while you work would then be optimum given the work situation. |
