Malcolm Myers, 63, was walking Yorkshire terrier Buddy on Wednesday when a tree came crashing below a garden.
Mr Myers was struck in the back and the neck by branches, and was buried by foliage as he passed the Sowerby Institute near his home in Thirsk.
The ex- bodybuilder handled to totally free himself with help from ten-year-old Buddy.
He said: “I’m extremely lucky to be alive, the physicians don’t understand how I endured.

“It has actually been dreadful. I didn’t understand what had actually occurred, I heard this seem like thunder splitting.
“I was walking my Yorkshire terrier and he saved my life, he concerned my rescue, he came adding and began digging me out.
“I’m having flashbacks of his head under a branch as he was digging, he was actually striving to get to me.
“Adrenaline was beginning, while the dog was desperately digging to get to me, he made a location where I might see daytime.
“I remained in darkness, I handled to seize his paw, he is a really strong little fella. He handled to help me make it through.
“I didn’t lose consciousness but it was just darkness.”
After the experience Mr Myers went directly home and had a cup of tea and the next day went to the GP, who feared he had back damage although x-rays revealed he had bruising.
Mr Myers included: “They said it will become worse prior to it improves, I’m returning next week and have actually established a limp.
“The branch struck me on the back of my neck, and a log struck me in the back.
“Hopefully I have been through the worst of it.”
North Yorkshire Council’s interim head of highway operations, Jayne Charlton said: “We can verify we are examining after branches fell from a horse chestnut tree in a personal garden and arrived at the neighbouring public path.
“A member of the general public notified us to the event, which we reacted to right away, closing the path while the particles was cleared.
“We received a more report that a man walking his dog was struck on the back by a big branch, while a smaller sized one struck him on the head.
“We have made contact with the landowner to inform them of their responsibilities with regard to the tree, which is subject to a Tree Preservation Order.”
