Luke Robinson, who began the trek to Boston from Austin, Texas, with canine companions Murphy and Hudson in March 2008, crossed into Massachusetts at about 4 p.m. Thursday, after walking more than 2,300 miles, The Boston Globe reported Friday.

Robinson said the walk is designed to raise awareness of canine cancer after his beloved Great Pyrenees, Malcolm, died of metastatic bone cancer in 2006.

"The most important thing about our mission is really just sharing Malcolm's story and going out and talking to people about canine cancer and comparative oncology," Robinson said. "This is not a race."

He said Honest Kitchen, a California-based dog food company, has been keeping Murphy and Hudson fed while the trio has been staying in their tent and with host families along the way.

"People have been very gracious and generous," he said.

Robinson said he is planning to walk the final mile June 19.
