Welcome to Corgi Nation! I saw your blog about a spooked Clue. My little man Reed is going through the same thing right now. He hates all things loud and cacophonous! He is about to complete in first obedience class. He does great at home practice but in class he is very nervous and anxious. He hate being in the car unless his Penelope is with him. Not sure if he will outgrow this or it may just take time. Good luck with Clue and let me know if you find any tricks to ease the stress!
Rebecca, yes, people are always thinking that Sidney is a cardigan or a mix! They think Pembrokes are born without tails. I try telling them that Sidney has the "natural look". I thought I saw in one of your pictures that Clue had a longer nub; one og my friend's corgis has his tail like that too. It's adorable.
