Technically speaking, the Landseer is a variation of the Newfoundland breed. It is actually only recognized as an independent breed by a few select kennel clubs in Europe.

The main difference between the Landseer and Newfoundland is the coat color. The former gets its unique markings from a piebald genetic mutation. This results in varying degrees of white coloration over the body.

However, their faces are almost always predominantly black with white spots on the top of the snout and forehead.

Weight of the Great Pyrenees Mountain Dog: 85 to 160 lbs

Something interesting is the fact that these doggies are considered among the dumbest of all dog breeds. This does not have as much to do with intellect as it does their ability to learn in general as afghan hounds can be quite stubborn and have very poor response rates.

20. Dogue de Bordeaux

Height of the Dogue de Bordeaux: 23 to 27 inches

What Is The Heaviest Dog Ever Recorded? 

While the English Mastiff is the largest dog by height and weight, it was a Saint Bernard named Benedictine that holds the title of the heaviest dog ever recorded. The giant dog weighed in at an incredible 357 lbs taking over from Zorba, the Old English Mastiff who had previously held the record with the recorded weight of 345 lbs.

What Is The Tallest Dog Ever Recorded? 

Great Danes are known for their great height ranges which is why it comes as no surprise that Zeus the Great Dane is considered the tallest dog ever recorded. This gentle giant measured 44 inches from the feet to withers when standing up. This height was further exaggerated by the dog’s lean frame.

What Is The Longest Dog Ever Recorded? 

Zorba the Old English Mastiff holds the title of the longest dog ever recorded with a head to tail length of 8 feet and 3 inches. What is interesting about this specific dog is the fact that he previously also held the title of the heaviest dog in the late 80s, weighing more than 300 lbs.
