First of all, according to the book:Teaching Tricks to dogs for dummies, all tricks and commands are the same. so everyone is right.
My dog is a silky terroist( I got that from someone on this site) and he can do:
among sit, stay,beg, etc.
he can roll over, shake hands, shake on command( his body)dances, gives kisses. He can take a bow. but, his two specialities are:
he does a show trick where if you put say a $1 bill in one hand and a $20 in the other and ask him which one he wants, he always takes the higher amount. I don't know how he does it!
Also, (I taught him as a pup to "sick" roaches.) I was living in Charleston, SC at the time and the Palmetto bugs are horrible. Now,( he is six years old) all I have to do is scream and he comes running, catches the bug in his mouth, carefully takes it "outside"(command) and "drops it" (another command). He is my best buddy!!!
