#10 Shelties have a lot of energy and need to be able to run.
They thrive on agility or flyball training because they are mentally and physically exhausted.
#11 Shelties have been popular family dogs for many years.
Because the demand for puppies is very high, there are many poorly bred Shelties available for sale.
#12 If you are looking for a puppy make sure you find a trustworthy breeder who will test their dogs for genetic diseases and make sure they have good characters.
To get a healthy dog, never buy a puppy from a mass breeder, a pet store, or a breeder who doesn't have health checks and guarantees.
