what to do with a stray pitbull

hey y'all, what's good. this is going to make me sound like the worst human ever, but i desperately need community help. we have a stray dog (female – pregnant – large ~60lbs) who keeps running onto our large property. we can USUALLY handle this on our own, but she's started to approach myself & my godson (4yr old) while we're outside, and i can't risk him being hurt by an overenthusiastic untrained dog.

animal control hasn't been any help (never have been). humane attempts to run her off have failed. SIL got her into her truck and even went to the vet (no chip).

she's lovely, friendly, and desperately wants a home. but we literally cannot keep her on the property. does anybody have any advice on a good place to take her.

thanks in advance.
