Sitter Needed For 1 Dog In Seville

I have one dog, Scarlet who needs a companion during the day while we undergo a separation anxiety protocol over the next couple of months. Her ideal pet sitting would be laying on the couch with someone to cuddle with. She's very shy, but once she comes out of her shell, she is super cuddly and chill (she'll sleep all day next to someone if they have limited mobility or aren't feeling well). She can be spicy about someone approaching the house and she's picky about other dogs, but with the right person, she is super low maintenance and quiet. She's just super anxious about being left alone and having a very hard time. She needs a friend during the day while we train!
