For 2 Days Now Our Dog Snauzer/poodle Mix Seems To

for 2 days now our dog snauzer/poodle mix seems to not have any strength in her left hind leg and when she goes outside she runs and then falls over - could she have had a stroke? she seems to be going in circles in the house and we put down rugs all over as the wooden floors and ceramics are slippery for her now
