Today I braved myself to watch the videos. First it is hard to watch the servere case but at the same time, an informed owner it good. Karlin does a great job informing people.
My question is while watching the less severe video of Chester, I saw so much of my lab in it. Could a lab had this? She was in no way as bad as Chester and I never heard her yelp but she did have one side that when brushed her back leg frantically scratched her tummy. Pull brush away stop, start again, the scratching started again. She also always rubbed up against couches and beds (I blocked off the living rm for 15 yrs as I had a white couch in there). She often rubbed her head up and down the fence, lawn and rug.
I am just curious because looking at Chester was like watching our lab - minus yelping or difficulty when walking.
