Is There A 200 Pound Dog?

You’ve probably noticed that some of the breeds on our list, particularly males, can weigh anywhere from 100 pounds all the way to 200 pounds or even exceed this impressive number.

A good example is the English Mastiff which is the number one dog on our list and it can easily weigh anywhere from 160 to 230 pounds. Let’s not forget the Boerboel which is a strong and large breed weighing anywhere from 150 to 200 pounds, similarly, the Spanish Mastiff can also weigh 200 pounds, as well as the Tosa Inu.

Of course, you need to keep in mind that these weights are approximate and can vary widely within the breed itself. Not all individuals within these breeds will reach 200 pounds. Diet, genetics, gender, and overall health care can all influence a dog’s weight.

If you’re looking for a dog of this size, it would be wise to consult with breeders or other professionals familiar with the specific breed to understand more about what to expect in terms of size and care requirements.

Also, just because a breed has the potential to weigh 200 pounds, doesn’t mean that they all will or should, so you need to make sure that the real reason behind their weight is not obesity. According to Malcolm Weir, DVM, “Obesity shortens a dog’s life and makes them more likely to develop disease.”

He also points to research that showed “that being even moderately overweight can reduce a dog’s life expectancy by nearly two years compared to their leaner counterparts.”

Is There A 300 Pound Dog?

There are no breeds that weigh 300 pounds and while certain individual dogs might reach or exceed 300 pounds it’s not standard or typical for any breed out there.

The English Mastiff is one of the largest dog breeds, and some extraordinary individuals have been known to weigh over 200 pounds. The record for the heaviest dog was an English Mastiff named Aicama Zorba, who weighed 343 pounds in 1989. Zorba was displaced by an even heavier dog, a Saint Bernard named Benedictine, allegedly weighing 357.1 pounds.
