Greater Swiss Mountain Dogs truly are beautiful animals and this is what attracts some people to the breed. Although they are so beautiful, they can sometimes be challenging to raise, can be prone to health issues and require more training than the average dog. It is really important that you do as much research as possible, meet as many Swissies as you can, and talk to several breeders before deciding this is the right dog for your family. They were bred to be working dogs and so they need daily exercise, mental stimulation and a job. Although they do love their naps and downtime, they aren't sedentary animals.
I highly encourage you to take the time to read all of the breed information on the Greater Swiss Mountain Dog of America website. This will not only help you be an informed puppy buyer, but also set up you and your GSMD for success and happiness.
