Thanks for posting the puzzle demo. I have a 12 week old bi-black who looks like Ollie and acts like Jasper. I have run through every idea to keep her stimulated.
Tty putting some kibble into a doggy blanket and roll it up. They love tp forage in it. And of course the Baaaaah game, which needs 2 people... see recent video.
Food aggression can be a problem I had a rescue who had this , was told that dogs like their own personal space around food bowls and also don’t always like to share a bed , depends on the dog of course , beautiful colours 👍 good idea to have individual puzzles
