He said his wife used her coat to keep Roxy, the short-haired boxer, warm and took her lead from the dogs who dug a hole in the undergrowth to sleep in, following suit.
"One of them was cuddling [her] and one of them was on guard and the other one was looking for food," he told Global News.
None of the dogs left her side, he added.
Over 100 rescuers combed the wilderness near Eagle Mountain to try and find Mrs Poitras after her husband reported her missing on Monday. Two helicopters were also used in the search.
Eventually, one group of rescuers heard faint cries for help and the dogs' barks and were able to locate them in a remote area.
The rescue team said she was "alive and in good condition" quite far into the Coquitlam Watershed and off trail, in dense bush and swamp.
Mr Poitras said his wife was recovering and will be released from hospital this week.
The couple are looking forward to "quiet, peace, walking dogs, visiting family" now the ordeal is over, he added.
