Gees sounds like if Dude could talk he'd let you know how much he misses and loves you too. Sorry, sometimes all we can do is the best we do.
I have a feeling that Jo has already a big place in your heart, not that he could ever replace Dude or really fit in his paws...lol He will make his own paw prints and they will be just as big with no time at all.
Look forward to seeying pics!
