Aw, geez...poor Barkley! Think the motion of the truck helped somehow?
Although it’s good that he was fine pretty quickly, it’s frustrating that you weren’t able to show them how he was reacting.
This is the second time he’s done this, of course. The last time, he was still in pain when he got to the vets, but there still wasn’t anything she could feel, except that he’d scream if you tried.
Just keeping an eye on him.
