AIO For Charging Due to Property Damage?

Am I overreacting or justified? I 24 live with my mom and stepdad, I pay my due and do my part in the house not just living there. The problem is that my stepdad brought a new puppy behind our backs (I have a 5F maltipoo, he knows that and has lived with her for years and knows my dog doesn’t destroy things and basically just barks at people but runs away once you look at her direction) he asked me about getting a new dog and told me to help him take care of her (I would love to but I had just lost my 10M cat and my dog has anxiety that turns into seizures and doesn’t like to be with other dogs as she’s a quarantine baby) and I told him that wasn’t possible because we all work full time and my dog is able to fend for herself (she mostly sleeps all day) but he still wanted the dog and brought her one day when we were already at work and put her in his room.
Now the puppy it’s kinda cute and everything but who was going to take care of the dog? NOT HIM. The puppy bites and destroys everything that catches her attention, he is not training her nor spending time with her. After she destroyed basically everything in his room what did he do? Put her outside. The problem starts there, he knows I have plants which I grew from seed (I’m a newbie gardener) and they were in containers where? On the floor obviously. She ate 3/4 cucumbers, 2/4 tomatoes, 4/4 basil, 4/4 lettuce, 2/2 watermelon, destroyed not only the plants but also the containers in the span of 2 days. I was beyond devastated. He saw everything she did because I have cameras outside. He swept the soil from my plants after coming home from work every time she murdered my plants hoping for me not to see. She destroyed my garden hose, my mom and I’s garden shoes, the bug screen I had for whenever I left the door open and is chewing the camera cables. What did he do? Minimize everything. The dog did something? “Ahhh it’s a puppy with a bunch of energy” “Ohh I saw she did that too” and what was his reasoning? “YOU left the plants on the floor knowing she was there”
Tf? Where should I plants on the mf roof? I had my plants there long before he got the stupid ideas of bringing the dog like he was smuggling drugs into the house. I got tired of his “yes I’ll pay you back” and never getting no cents back. She’s been here for about 2 weeks already. My dog can’t go outside because she’s a large breed and my dog gets her feathers ruffled. I have my plants in cages basically and even then she gets into my containers and lays in my remaining tomatoes breaking them. I’m TIRED. What did he do? He bought a cage and leaves her there during the day and lets her out in the evening. What did the puppy do? Watch breaking bad and jump the fence and gets out of the cage. Don’t get me wrong I love animals but if I do something like take care of HIS dog he will except me to do everything for her and that will be an extra responsibility for me. I can’t do that I’m tired after work and still tend to my plants and dog and he still wants me to take care of his dog. I can’t be doing that.
The problem came to a head when I deducted $250 from this months rent money because he isn’t paying me back all the things. What was his response? “The dog did that you can’t be charging me for things the dog did” and “It’s an animal and your fault for leaving the plants there in the first place” and my favorite “it’s an injustice, plants are not expensive so you can’t be charging me that amount without telling me first” “I can’t be throwing money to the trash” (implying my things don’t matter and I have to suck it and let the dog be a dog)
My response? I told him I was moving out because I can’t be throwing MY money and time to the trash them fucker. Now he is panicking Beth’s can’t afford the house (we are renting) alone (I moved with them because his credit is trash)
My mom is fully on my side but he can’t see that the problem is him. Neither my cat nor my dog did anything to his things and now I have to just smile and watch him tear up my stuff? Fuck no. He went crying to everyone about his money and I had to give it back to get him off my back (stupid decision I guess) and now he is acting all stupid with the tail between his legs now talking to me. Over the phone he’s a big strong man but face to face? Can’t look at you directly to your eyes. I told him I need to speak with him but he’s hiding in his room.
Did I mention his age? He’s 60 something the big guy who can’t communicate. If he doesn’t talk to me instead of talking behind my back with everyone I will have to wait for him by the door and make him have a conversation with me.
I feel terrible about the dog it breaks my heart but I can’t be giving him no more leeway letting him not have any responsibility about shit.

Sorry for the long post I didn’t have anyone to talk about it with, sorry for all the spelling errors this came down today and I needed to blow it somewhere.

So am I overreacting by changing him money because of the damage his dog did to my property?

Thank you for reading:)
