Dog in a bar

[rebbonk]

A man walks into a pub with a dog. The dog looks round, sees a trilby on a barstool and attacks it.

"OI" says the hat owner "what the hell???"

"You should look after your stuff" says the dog owner.

"Oh, so that's your attitude" replies the hat owner.

"No" says the dog owner

Spoiler:

"it's your attitude"
