the best method thats seems to work with mine is: hold the
object you want you dog to learn, for example: if you want your dog
to know what TOY means, hold a toy, get the dogs attention, say
"toy" then hold the toy out to your dog. your dog should sniff the
object your offering to him/her. while he/she is sniffing the toy
tell the dog what it is, say "toy". then stand straight and hold
the toy away from the dog, say "toy" again and then throw it,
saying "go get the toy" do this every single day for about a week
and then tell your dog "Go get the toy. Toy. Toy. go get the toy."
your dog should go get the toy. if you want him to learn a word
like a command, sit, lay down, speak, then you have to show the dog
what sit means and then reward him/her. for example say "sit" then
force the dog into a sitting position, then praise your dog, even
tho u did it for him/her.
