pug mix dogs

How to teach my puppy to be gentle with smaller dogs.?
I have 4 month old, Olde English bulldog puppy currently 20 lbs on his way to 50 pounds. We live with my sister who has a 1 year, 5 lbs yorkie and visit my mom who has a very nervous-making russel 4 years old pug mix. My dog CRAZY is compared with them, constantly attacking, jumping back into the jar. She bit her yorkie's ear and made him bleed (tyson call now.) I do not know how to keep the peace. The pitcher has started growling and snarling at her, even when she is just about him and the puppies have to spend the night dodging it. I just want everyone to be able to live in harmony because if she is younger and she will have to be the one to go. I'd appreciate any advice. THANK YOU!
Have you tried a spray bottle? Sometimes, squirting them distract them enough so they stop the behavior. Then after a while, you just hold the bottle and the dog will stop. I hope not left alone at any time. Definitely recommend supervision. Place copy in a box when you can not see them. In addition, try to reward the bulldog with a treat and praise when he is acting very well with the puppy. Teach bulldog who needs to establish when the puppy comes around. This help her learn how to present and the puppy will not be so afraid of it.
