She chews on everything and ate her bed💔

Hello!! Ivory is a 6month old Doberman and she chews on everything and recently tore her bed apart and idk what to do :( whenever I see her doing it I try to give her an alternate toy to play with like her balls and hard toys so she can teeth on them but whenever I do she just goes the other way and grabs another toy. Idk abt the bed tho I always take it away from her when she eats at it but I was gonna for five second an I came back and it’s ripped apart and idk if I can see it and even if I do I know she’s gonna tear it apart once more. I wanna buy her licking mats and other things but I don’t have the money and my grandma throws a fit whenever she has to buy smth for ivory :( idk what to do or how to get her to stop i even try to give her treats when she doesn’t eat smth she not supposed to but it isn’t working
