Congratulations! I know Mr. Wilson will bring joy to your family! I have a six-year-old female Maltese. I can remember her potty training days vividly.
I wanted to add just a little to this post - be patient and above all, consistent. It may take up to 7-8 months to train a smaller breed such as a Maltese. I thought this was insane until I compared the difference in training times between my larger yorkie-poo and my Maltese.
When trying to determine what method is best for your family, consider how you want Mr. Wilson to potty in the future. Will he be leash walked to potty? Will he have a doggy door? Do you live in a condo? Will you be using an indoor potty system? You've got a lot of choices. Just stay consistent and he will follow your guidance.
Go to my website on small breed dogs. You'll find great information on potty methods and training. I'm a Kennel Manager and also write an informal blog about the dogs and issues I see in the kennel. You can subscribe to it through your Yahoo homepage or any other XML reader.
