drop it......leave it how do I ?

how do I teach my pups these tricks?......I would love for them to know drop it and leave it .....please if you have any links or ways to teach these tricks please let me know thanks in advance!:D

What i did with cami was whenever she would grab something off the floor i would tell her to *COME* and when she did i would take whatever was in her mouth, put it next to her on the floor and tell her *Leave it* while having her in a sit/stay position. Then i would tell her *Okay* and she would grab it again.

Hope thats of some help. For drop it, i did it the same, except instead of telling her to *Leave it* I would tell her to drop it. :)

I put a treat under my foot and let Lacey see it then tell her leave it and if you're quick enough when she tried to take it I put my foot back over it , then tell her ok and let her have it. It worked for me! I'm sure there's different ways though. And for drop it I just praised her , till she got it but I use the word give. :)
