i think this lady is trying to pawn her horse off to me and i dont know what im doing! its way too hot for him i need help!

so about a month or two one of my moms friends started paying me to go feed her horse everyday and i love animals and need the money so obviously i said yes. now she has me cleaning his pen and taking him out daily and dumping pounds of shit that weigh more than me. i have to do everything now she wont even come to see him if i think something is wrong or i need help.

yesterday it reached 110° and when i was feeding him he was drooling, i know thats normal but i also know hes super hot. he’s not in a barn hes just in a pen outside. we live in the desert and now im attached to this horse and just thinking about him being out there makes me cry.

any tips to help him keep cool, i wish i could just bring him home lol. he’s scared of water so that’s out of the question, hes 28 if that helps. pretty fucking old so that makes it worse. i don’t know what to do. why would she even get a horse if she doesn’t want to take care of him.
