omg!!!!! i'm freaking out snow is in heat

omg!!!! idk what to do

so far i've got her senivitive baby wipes to clean her private part so she feels clean at all times i've got her some diapers grabed so blankets to make her comfortable

am i missing anything? btw I was always planing to spay her but my vet was booked until nov.24

I've tried other vets but they are booked

and she has to get a umbilical hernia removed

the same time she gets spayed any suggests or advice or something about all of this?
