Is it a good idea to put your dog into shelter if you can't control it anymore?

Lately my female dog has been acting aggressive (barking mainly but just last week she tried to lunge onto another dog) with other dogs and nearly attempted to drag me to kill a cat; luckily nothing happened and the cat climbed on time but it took the 3rd super loud command for her to stop.

It hurts me because I've raised her since she was a puppy but she changed suddenly just 4 months ago. It's like a different personality, a side I never knew in her.

I don't want to then end up with a fine or possible jail time if this goes too far. Is this now the right time to place her in shelter? I don't think I can control her anymore. She's changing into something I don't want to be liable for. I've heard that if a dog taste blood for the first time or attempted to (she would've done so if she had succeeded in killing he cat), it's too late by then. Is it a good idea to give her up? I can't take it anymore.

I think I've made a mistake in selecting a Presa Canario as a first time dog owner. I really thought female Presas (female dogs in general) were less territorial, more docile and easier to handle/tame.
