Ava is part of our team of Mad Dogs. She had some pretty big PAWS to fill after Alice but she is as much of an explorer as her beloved predecessor.
Ava is a rescue pup as was Alice. No one wanted to adopt Ava as she had been burned and mistreated and left to die. When she came to us she had a black husky head on a brown husky body.  She loves the life of adventure and always ready to travel but she is great at sitting in on meetings too.  She is a trained therapy dog and knows when its time to work and be patient..this is not easy for Huskies as they are high energy all the time!

Ava deserves her own reality show , web site and twitter account as she has so many followers and admirers.  She has been seen on TV , featured in the NY Times, part of a major expedition on the High Seas, always photographed yet she is very grounded.... just don's ask her for her autograph.
Ava has logged tens of thousands of miles on both land and sea expeditions.
Our founding Mad Dog team member. Alice was thrown out of a car in Greenwich village a few days before Christmas 1995. We adopted her from our friends at the animal hospital next door to our office and took her on her first of many ice diving expeditions.  Alice traveled as far south as Key West and far North into the wilds of Canada.......She had a set back in May 2004 when we discovered she had an inoperable brain tumor. After a month of radiation treatments, lots of love and support from family and friends she was still chomping at the bit to travel. She was 13 and going on 2 again and showed us her true Mad Dog grit to the end. She had the spirit of a true explorer and adventurer that everyone loved. Alice was the "Brains" behind our operation and well known around town for her stunning good looks and charm. She is a legend.
Late Great-Alice
