I'd rather have her in a muzzle when socializing w/Alice
But how long for , life , 24/7 ?
I have had infection every time I got bit & my right hand is now 50% disabled from bite damage so don`t take no chances & get antibiotics . Just tell the hospital that is was a stray dog & you have no idea where it came from or where it went .
I know you have a hard decision to make but like you I gave mine another chance & it turned out badly , whatever you decide respect for that .
