Ava

Ava is the newest addition to our team of Mad Dogs. She has some pretty big PAWS to fill after Alice but so far so good.

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. The little hair she had was singed yet she was a stunner nonetheless. She loves the life of adventure and always ready to travel but she is great at sitting in on meetings too.

Late Great-Alice

Our Mad Dog Icon.  Sadly she passed away last year.  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. As she was already familiar with cars, we decided to start taking her on our expeditions, and the rest is history! 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 is 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 kept on going. Alice was the "Brains" behind our operation and well known around town for her stunning good looks and charm. She is missed by all.
