Rocky's Health Crisis: Immediate Help Needed

My Dog Brownie had her hind legs stop working and now this. I really don't have the energy for this anymore. I'm tired, i'm broke, im screaming into the air and there is nothing i can do anymore. I really don't know if there is anyone out there that can help but if there is please help me with my Dog Rocky because this is something more recent as of this week and is severely getting worse everyday. It is a tooth abscess and needs help now and i cant even get a doctor to see him unless i do a walk in and at this point its leading the infection up towards his eyes. PLEASE HELP WE NEED HELP.
