Bonjour
I have some short ones too

When is the most likely time that a stray dog will walk into your house ?
When the door is open !
What do you get if you cross a dog and a cheetah ?
A dog that chases cars - and catches them !
What happens when it rains cats and dogs ?
You can step in a poodle !
What kind of dog does Dracula have ?
A bloodhound !
What is the only kind of dog you can eat ?
A hot dog !
What kind of dog sounds like you can eat it ?
A sausage dog !
What did the hungry Dalmatian say when he had a meal ?
That hit the spots !
What do you do if your dog eats your pen ?
Use a pencil instead !
Why don't dogs make good dancers ?
Because they have two left feet !
What do you get if you cross a Rottweiller and a hyena ?
I don't know but I'll join in if it laughs !

Those are good ones..

I've been sitting here laughing away to myself
