Great Pyrenees were bred in cold weather and their thick layer of white fur matches it.Due to all of their fur, they require a lot of brushing and grooming, especially in hot weather.When compiling or looking at lists of the top 10 guard dogs it is very important that it is fully understood what a guard dog is.Many people confuse a guard dog with a watch dog and attack dog or think that they are just all different names for the same thing.The human shepherd would in many cases come to the guard dog's aid with a weapon, not letting the dog fend for itself.The following breeds are the best at watch dog barking: If the risk is from human intruders, a suitable dog can be simply trained to be aggressive towards unrecognized humans and then tethered or enclosed unsupervised in an area the owner wishes to protect when he is not around (such as at night); the stereotypical "junkyard dog" is a common example of this.
They are different from the smaller watchdogs in that they do not continue barking, they take action.
Hip dysplasia is a common problem in the breed, as is lymphsarcoma Rottweillers have an overpowering need to be dominant, and only a few people can successfully deal with this.
They also have a tendency to "mouth" things, hands in particular.
When they grow up, they get as big as 80-120 pounds and their average lifespan is 10-12 years.
They are known to be rather obedient, as well as very loving.
