how to stop holly from jummping on people?

When she goes to jump on you, left you knee to block her and say "no jump". Do it gently, just enough so she doesn't touch you. Every dog I've had has been trained this way. It always works. Max will look like he is going to jump and I say no jump. That's all it takes now.

Get a squirt bottle! Have it handy when puppy gets ready to jump. Squirt and say NO very firmly. If that doesn't work, get a no-jumping lightweight harness to put on her. It doesn't hurt the animal and they sure learn quickly that there is no need to jump to get attention! Good luck!

What you should do is correct her right before she jumps on your grandma. Just give her a "bite" with your hand when she gets ready to jump and make a sound or say "no jump" or just plain "no". It will take a few times before she gets it.
