I have been trying for about 4 days now to teach my dog "Paw" but everytime i try she just looks at me with this dumbfounded expression and has no idea what I want her to do. i keep picking up her paw and saying paw at the same time hopeing she will realize thats what it is, but she doesn't. I know if i can get her to put her paw on my hand once by herself It will be a cinch. I have tried treats and stuff but it is hopeless if the dog doesn't know what you want her to do. She has sit down perfectly though...
