He may feel like the inside has become Peggy's domain and he thinks he can't come in.

Yes, think that's the point!

My mother told me today that Reinhold had brought him in yesterday to his favourite spot on the heating, and he petted him there and talked to him. Dino seemed to have enjoyed that for a while and even purred, but then it seemed to have hit him that he's in Peggy's territory, and he hissed and wanted to leave the house.

Maybe they should continue doing this, especially when Peggy is not around.
