Are these some of Zack's friend?

I just read this article from the NY Times about dogs and them being a "woman's best friend" and it made me hope that they are not just a fashion accessory. Zack wouldn't be caught in a sweater, although Skippy (almost 15) loves his sweater to sleep at night. :) See the link in the left hand column called "women's best friend?" if you wanted to read the article.

Zack update...

Low tides are here as the full moon approaches. Look for updated photos of Zack running at low tide. In the meantime, where is a photo of Zack after he finished his Doggie Yoga.
