Yes that’s an acupuncture needle in Sheldons head! With other needles in other areas this point is called Yin Tang and its a Chinese relaxation point.
Sheldon seems to have responded really well to the acupuncture already! This morning he was able to jump his front 2 paws up on the bed and stand on his back legs which is something I’ve never seen him do and this afternoon out of nowhere he just galloped down the garden!!! Honestly in the 4 years we’ve had him in saw him run once and he stumbled over his own feet and fell i think he’s definitely more relaxed and chilled and you can even stroke him down his back. If I was to do this before his back spasmed and he’d grumble and sometimes even snap at you 👏👏👏 thank you so much for your help ❤❤
