Pyrenean Mastiff vs Great Pyrenees: Lifespan

Pyrenean Mastiffs live slightly shorter lives on average, spanning from 8 to 12 years. Great Pyrenees typically live 10-12 years.

Pyrenean Mastiff vs Great Pyrenees: Tolerance to Children

Pyrenean Mastiffs are known for being excellent with children, though every dog is different! They tend to be gentle giants and incredibly tolerant.

Great Pyrenees dogs are family-loving. If you have a child in the family, they’re sure to bond with and love them. However, they may be stand-offish toward strangers, which can include children they don’t know.

With any dog, especially a giant breed, it’s important to teach proper manners. Never allow them to jump on people, even as puppies, as bad habits like this can be hard to break in adulthood.

Children should also be taught proper behavior and gentleness with dogs. Don’t let them touch the dog’s food, get in their face while eating, or climb on the dog’s back. They should pet dogs gently and never hit or tug on them.

Always supervise children and dogs together. Even if you trust them both, mistakes can happen, and someone can end up hurt!

Pyrenean Mastiff vs Great Pyrenees: Energy Level

Pyrenean Mastiffs are low-energy dogs. Like any dog, they still need exercise. They benefit from several short walks throughout the day and playtime in the backyard. Due to their size, their joints are fragile. The AKC recommends against walking them on cement and notes that long walks can be detrimental to a puppy’s growth and health.

Great Pyrenees have slightly higher energy, but they’re built more for endurance than sprints. It’s in their nature to conserve energy, as they’d need it to save livestock from threats. They need at least one long daily walk and benefit from playtime in the backyard as well. Like Pyrenean Mastiffs, Great Pyrenees are giant dogs, and you should take caution not to over-exercise them as puppies.

Pyrenean Mastiff vs Great Pyrenees: Grooming Needs

Pyrenean Mastiffs are higher-maintenance in the grooming department, though they tend to shed less than Great Pyrenees. Their coat should be brushed once every three days to prevent mats and tangles. Check them regularly for mats in commonly-tangled, harder-to-reach places like under the armpits and between the toes.

Great Pyrenees dogs have coats that resist matting and dirt, but they still require care. Brush them once weekly to remove any snags and to distribute their natural oils. This will keep the coat looking healthy and sleek. Regular brushing will also lessen the shed you’ll see from your Great Pyr year-round.

Pyrenean Mastiff vs Great Pyrenees: Drooling Level

Great Pyrenees are moderate droolers. You may have to wipe their face occasionally and clean regularly beneath the water bowl. They might also drool on the floors, furniture, or people—particularly when they’re begging for a treat!

Pyrenean Mastiffs are even heavier droolers, and you’ll definitely have to keep up with wiping their mouths and cleaning up behind them.

Pyrenean Mastiff vs Great Pyrenees: Barking Level

It’s unlikely that your Pyrenean Mastiff will develop problem barking behaviors. They typically bark only to alert. Great Pyrenees dogs are moderate barkers and more likely to bark excessively. If your dog barks too much, this can be a result of training or boredom.

Start by ensuring they’re getting plenty of attention and exercise. Next, make sure your dog hasn’t developed separation anxiety, and they aren’t being left alone for great lengths of time. Lastly, teach your dog to speak. Yes, you heard that right!

You want your dog to bark on command so that their barking is somewhat under control. Then, you can give the command and praise your dog when they stop barking. This is the beginning of teaching a “quiet” command.

Once your dog has it down, you’ll be able to shush them easily when the mailman arrives, saving your eardrums from their loud barks!
