According to The Old Farmer's Almanac, the Dog Days of summer are traditionally the 40 days beginning July 3 and ending August 11, which coincide with the dawn rising of the Sirius, the Dog Star. That being said, it's also the hottest part of the year as we all know.

It's fitting that we celebrate National Mutt Day on July 31. But what is a mutt? Is it a mixed breed dog also now called a designer dog?

My friend Julie has a Berne-Doodle which is a Bernese Mountain Dog crossed with a Standard Poodle. He's adorable and huge.

Friend Brian has a mix of pit bull, mini pincer and Chihuahua and 'Chevy' is beyond cool.

Friend Doc has a lab-Akita mix and he'll tell you 'Steve' is the best dog ever.

According to nationaldaycalendar.com, National Mutt Day encourages us to embrace, save and celebrate mixed breed dogs twice a year on July 31st and December 2nd. The website indicates that shelters are full of mutts needing homes. My research indicates our best friends are wonderful mixes that are adored by their families.
