The happiest dog in the world is not his happy self today

A lot of people love Henry and this is for all of you.
Henry is out of sorts today. He and Slinky had a bust up last night and his ear and paw is sore. The purple spray on his neck was my first attempt to spray his ear and he moved away. It's a antiseptic and I use it on the horses, dogs and humans.
He's not badly injured, but I need to keep them separated whenever there's food around.
The up side is, he's back in Mum's cabin.
The purple/pink spray is cetrigen, a staple for most horses owners where I come from https://au.virbac.com/products/sheep-first-aid
