Hi guys sorry if this is in the wrong place but I only really made this account to ask for some help!

My mum found a frog yesterday and she 'thinks' she shut the door on its legs or something -_- Either way I moved it to the end of the garden since it seemed able to prop itself up on its front legs just fine (it's back legs are kind of immobile, only really moving when i prod them). This morning I went back to check and it hadn't moved at all so I've relocated it to a brush by our door for cover on some damp soil..and he's kind of moving around and croaking..Not sure what to do...
