For many dog lovers, the bigger the dog, the better! It’s sometimes shocking to see a dog who’s nearly as tall as his owner, weighing in at just as much.

Large dog breeds aren’t always tougher to handle than their tiny counterparts, either, as many of them are simply gentle giants.

In no particular order, here are the top 10 largest dog breeds:

1. Irish Wolfhound

Although not the heaviest, the Irish Wolfhound is considered to be the tallest of all dogs. This breed, which is often described as giant and rather commanding, is regarded as an excellent companion for many families today.

An adult Irish Wolfhound male generally stands at a minimum height of 32 inches tall and a weight of 120 lbs. Its female counterpart, on the other hand, normally stands at least 30 inches and weighs 105 lbs.

2. Mastiff

Towering at a height of at least 30 inches for males and about 27.5 in for females, and weighs at a range of 120 up to 200 lbs. or even more, this large breed must have had its name taken from the Latin word “massivus” which means massive- surely a perfect description for its huge size.

3. Scottish Deerhound

This agile and long-limbed breed, which was once bred to knock the wind out of stags in the Scottish hilltops, is on the largest dogs list because of its lofty height, about 28 to 32 in, and sometimes even more, and weight of 100 to 110 lbs.

4. Great Dane

  1. I have two Great Danes, a 160 Pound male, and a 115 pond female. They are Therapy dogs that are part of the Tail Waggin’ Tutors program at a local school, and they are much loved by students and school staff. The upsides to Danes are many. The vet bills are a consideration as they age…..the bigger the dog, the bigger the bills!

    We have a Newfie/great pyro mix, a Chessie, a Bernese mt. Dog and our “little dog”…a Golden! I agree that big dogs are easier and a lot less drama! They are all so friendly, loving & smart. They are easier to train and are great with kids. A little drool and a lot of fur but worth it all. They think they re lap dogs but all my babies are great cuddlers.
    Big dogs rock!

    Our largest dog is an English Mastiff. I have never had a more wonderful dog. She does not need a lot of exercise and is not destructive. She is the 3rd in our family over the years and only one of the 3 have been a drooler, but she is very tolerant and expects to have her mouth and lips wiped. They sound vicious, but I have never had one of them bite. Over the years we have had St Bernard, German Shepard, Bloodhound, Pitt, Schnauzer, Boxer and several types of hounds and my favorite is our English Mastiffs. We prefer rescues and I want to urge everyone that you can even get dogs with papers from rescues if you really take the time to find them . . . if that is your thing.

    We have a newfie, a pyr X and a newfie X berner; so lots of dog hair in my house. They don’t like being confined, and have ripped apart chain link fences, eaten gyp-rock walls, and climbed through open windows when left alone. Fortunately they never tried jumping over fences, just through. Wouldn’t trade them for the world though! The very worst thing about a giant breed is the short life span.

  5. My Great Pyrenees is no more a challenge because of her size (other than taking up so much room on the bed, as said) than my other 6 dogs; except collectively, we have a lot of stepping over and around to do — and that’s probably good for us. Also, I don’t know about the other breeds mentioned, but Pyrenees will take off and walk forever if they have a chance.

      I have a Pyre at home and he can be quite naughty about not coming until he’s good and tired, but he’ll happily play tag with me and my sight hound mix (she’s a good girl and the only one of my pack that’s allowed off leash anymore, there was one other, but he’s blind and mostly deaf now, so I can’t call him anymore) Yuki will run around us until he wears out and then he’ll ram me, which let’s me catch him.
