Do you know how much a Mastiff weighs? Most people are surprised to learn that the average weight of a Mastiff is between 160 and 230 pounds. That’s a lot of dog!

If you’re concerned about your Mastiff’s weight, talk to your veterinarian. He or she can help you create a weight-loss plan that includes dietary changes and an exercise routine.

With proper care, your Mastiff can reach and maintain a healthy weight – and live a long and happy life.
