Lost dog in London — Alert #2400

Hi everyone, my dog Sasha got lost. She had a seizure while on a walk around 9.45 am yesterday, 4th of November. Somehow Sasha got loose from her collar and lead. It happened on Montague Road W13. She was being strangely aggressive, so please don't get near her. I'm desperately trying to find her. If anyone sees her, could you please write below to let me know where and if possible, stay near her. Thank you so much
