Homer! We were playing with her and Homer and she went up to him and patted him and clearly said "Ho-ma". She repeated this a few times and when he got up and moved behind the sofa she looked round to where he had gone and said "Ho-ma" again. Unfortunately no video as we were all too busy telling her what a good girl she is and Homer that he's a good boy too. But here's another pic of her with him.
Ah so lovely,my niece and nephew adore Dexter....they were very nervous around him at first as my Sister ,their Mum, isn't a dog lover at all....... Your niece sounds really confident around Homer x
