Attacked by a Rottweiler in my society while protecting my dog

My younger brother and I were sitting in our society after finishing a walk with my dog, Woody. There’s an elderly uncle in the society who owns a Rottweiler. He was walking his dog when it suddenly noticed Woody and charged straight at us.

I immediately knew what was about to happen, so I stood up and lifted Woody into the air to protect him. The Rottweiler reached me and bit my thigh, leaving around six deep puncture wounds. My brother took the bottle and slammed it on the dogs head coz of which he ran away.

We then started walking towards the park exit, but when I noticed the blood( idk why but I have a phobia of needle and blood), I passed out and collapsed. Because of the fall, I ended up twisting my muscles badly as well.

Still shaken and trying to process what happened.
