The first one is Nashville's annual Music City Mutt Strutt which takes place on September 22nd and raises money for the Nashville Humane Society - which is where I adopted Claire! Some friends and I have formed a team called the SubWoofers [get it?!] and would love your help as we try to raise money for this cause. Claire and her pals are walking, too! Feel free to join our team!
The next one is Puppy Up, which is held on November 4th. The 2 Million Dogs Foundation puts on this walk to raise money for research that seeks to find common links and causes between canine and human cancers. I haven't yet registered for this walk, but I plan on doing so! Check out their website for more details about this awesome organization.
Of course, if you don't live in Nashville, you won't be able to participate in either of these events, but I'd encourage you to look for similar opportunities in your city!
