Dog Custody

My partner and I were together for 10 years. In our last 4, we moved in and adopted a dog together.

She cheated on me with my best friend. And her best friend both. Stole some of my legal paperwork. A bunch of technology. ( close to 800$ or so )

We had 3 dogs and 3 cats. She calls the cops on me and peddles 2 cats out of the back door.

She wants one of the dogs because of the paperwork.

I want to keep him because of the bond he has with his remaining brothers.

I'm not sure what I can do to keep him at home with his brother's. She's not moved out on her own. She's with her brother.

I am on my own. I pay all my bills and taxes. I buy high quality food for them and am slowly incorporating a raw diet.

Again. I just want them to stay together. They cry when I let them out and they are separated.

Might I add she's threatened court. But it's been 2 months and I've heard nothing. She's gotten her aunt to contact me trying to bribe me with one of her puppies and I told her it's not about the quality. It's the bond

Many thanks!
