Am I a piece of shit?

I am watching my neighbors dog for a month because he’s going through a nasty divorce. The dog isn’t trained at all and doesn’t listen for anything. So I have an extra long chain that he’s attached to and has to stay on it. He doesn’t come when called and if he wasn’t on it he could run into the road and get hit (I live my an extremely busy highway). I go out and toss the ball with him everyday and give him food and water and attention. He has toys and his dog house. He’s not house trained and likes to attack cats so he can’t come in my house. He has shade and everything. He’s well cared for here.

I was just out playing with him and he wrapped his chain around my leg and took off running and it ended up skinning my leg and really hurt me. In my pain I did raise my voice with him since he doesn’t listen to anything ever. He kept trying to wrap himself around me again so I grabbed his chain and rugged him in the opposite direction of me so I could limp out of his reach so he didn’t do the same thing and I did yell at him. It didn’t faze him at all. He didn’t even acknowledge that I was talking to him.

My boyfriend immediately started yelling at me that I was a dick and that I treat my animals like shit. I have a very well behaved Dane, 9 cats, and 16 foster kittens. My rescue people tell me I am the best foster they have and everything. I love all of my animals with all of my heart. I do yell at them when I get super frustrated, but yelling is usually as far as it goes. I’ll give my cats or dog a little boo on the nose or butt when they are being super naughty, but it’s not hard at all. It’s just a tap. I spoil my animals rotten. They are literally like my kids. I even spoil the neighbors dog I’m watching. I always buy him toys and treats, I bought him a pool to play in. I buy him stuff even when he’s not at my house.

Boy friend told me that he doesn’t ever want kids with me now because I’ll be so awful to them like I am my animals. To me that’s like telling him that he’s an awful dad to his daughter. I walked away because I didn’t want to listen to him say all these awful things to me and he called me a pussy and everything.

Should I just get rid of my animals? Am I a piece of shit?
