Great Pyrenees

Night barking is built into the breed. Flock guardians historically worked hardest after dark, when predators hunted, and a Pyr barks to warn intruders away rather than to alert you. You can reduce it by keeping the dog indoors overnight, covering windows that face a street, and giving it a quiet, secure room to sleep in. You are unlikely to stop it completely.

The breed has two dewclaws on each back leg, and the standard expects them. Their original purpose is debated; some suggest they gave extra stability on rough mountain ground. Whatever the reason, they need regular care. Check and trim them with every nail trim, because they don't touch the ground and can grow round into the skin.

Very few can be trusted off lead outside a secure fence. The breed's guardian instinct tells it to check the edges of its territory, and that territory keeps growing. A Pyr may walk calmly beside you for weeks, then follow a scent or sound for kilometers. A long line in open areas and tall, solid fencing at home are the safest approach.

For the right family, yes. Pyrs are usually gentle and patient with the children in their household and protective of them. Their size means they can knock small children over by accident, and their guarding instinct means visiting friends should be introduced calmly. Families who can manage barking, shedding and a dog that doesn't always obey tend to adore them.

They cope, but they are built for cold. A well-brushed double coat actually insulates against heat, so shaving is not the answer. Provide shade, cool floors and plenty of water, and exercise only in the coolest hours. Watch for heavy panting, bright red gums or weakness, and call a vet at once if you see them.
