So cute! Beckett was very much like that when we first adopted him at around 7 months of age. I asked the vet about his skin & the scratching, but was told everything looked fine. I chalked it up to the fact that he was (still is, somewhat) a rather anxious dog. Fast forward a few months - one of my other dogs was having digestive problems so I switched his food to a different protein (beef) from the chicken based kibble he was on.
Once I settled on a good food for Charlie I switched the other two dogs onto that food as well. Beckett's itching stopped. Completely. I could now even brush him without his back leg going nuts (that kicking/scratching move they do) Hmmmm. At one point I tried him on a turkey based kibble & the scratching started up again. Note to self - NO poultry for Beckett. He's fine on any other protein source, but scratches a lot (even though his skin looks perfectly normal) on poultry.
May or may not have anything to do with your issues, but figured it was worth mentioning.
