 Newfies can weigh anywhere from 100 to 150 pounds, and lifeguard Hope Taylor says these giant balls of fluff are great backups when it comes to water rescues. When there's very strong surf, I feel safer knowing that I have them. I don't always feel comfortable bringing that many people in, so having them here is very nice. Two full-time, full-size Newfies patrol Scarborough Beach, and they're training a third, Belle. She's not even three months old, and Wilford says she's already a super pup.
