3 into 1 won't go !

Bijou is getting upset because he wants to bring a 3ft long stick from the garden into his bed to chew it to pieces! However the doggie flap is only big enough for him.
When my back was turned he must have thought about it more carerfully and did manage to bring it in end on. Clever boy? -- Not so, when he makes a great mess of chewed wood bits for me to clear up.
