IS IT BAD TO KEEP A DOG OUTSIDE IN THE SUMMER

LIKE,,,,,,,, MORALLY,,,,,,,,,,,,,,,,

but physically too bc my mom wont let our pit bull come in the house bc she says "dogs are gross animals" or whatevers but lets a cat come in whenever it pleases...

i asked if we could bring him in after we give him baths bc he gets super lonely when hes outside alone and is outside alone but she still said no and just yelled at me for no reason:/

anyway yall what can i do to convince my mom to let him stay inside once in a while
