Aww, I'm sorry to hear about your older piggie

Although they are, by nature, social animals, they can be quite happy on their own as long as they have a bit of human company and a small teddy. If you make sure the teddy is the type that's safe for puppies (i.e. one that doesn't have plastic eyes, nose etc) then she'll cuddle in to that.
Give her a kiss from me (and my 2 piggies!)
