Now I have never trained my dog anything like , sit, stay, etc.
But even with my general slackness she seems to know a lot. Stuff she underdstands;
She knows her own name.
She knows the names of her two doggy friends and which is which
Dad
Outside
Inside
Lead on
Cheese
Biscuits
Downstairs
Bed bed
Walkies
Cat
Pigeon
Down
No
Frisbee
That's all I can think of right now but maybe more.
