Does my landlord have the right to be mad at me for having the internet shut off?

We had Verizon Fios and my boyfriend had the cable and internet shut off cause it was getting to expensive Our landlord was on our internet and now she is angry cause we will be piggybacking off of the duncan donuts wifi next door to us. She has not paid towards our bill even tho she said she would gvie us 25.00 per month. does she have the right to be angry with us? We will be getting a different internet provider next week but I'm not going to put her on it. Also she is telling me that the dog food I am feeding my dog is garbage. I'm feeding the dog Chef Michaels cause the first ingredient is meat apposed to corn. She wants me to feed my dog Beneful but I've explained to her that my dog is doing good on the food she is on now and I dont want to change but she is insistiting I change the food. She is also threatening to kick my 14 yr old son out cause he teases the dog and has hit her a few times hard enough to make the dog yelp. I have taken care of my son but does she have the right to threaten to throw a child out?
