6. Leonberger
Bred in Germany in the 19th century, the Leonberger was intentionally developed to resemble a lion. Adult males sport a distinctive mane of fur around their neck and chest. Weighing between 90 and 170 pounds, these dogs blend the traits of the Newfoundland, Saint Bernard, and Great Pyrenees.
Leonbergers are incredibly playful and maintain a puppy-like enthusiasm well into their adult years. They are remarkably agile for their size and love to swim. Unlike some independent livestock guardians, the Leonberger is highly motivated by human interaction and takes immense joy in participating in family activities, from hiking trails to backyard barbecues.
You forgot Grayhounds, I had mine for 10 years and she passed at 12, they are amazing creatures and companions.
I’ve owned many different breeds of large dogs. For the past 15 years I have been involved in a Greyhound Rescue group. We find homes for these dogs when they are retired from racing. I currently own three greyhounds. I have owned a total of eight. They are gentle and easy tempered..
