Information On Papillion Dogs?

Hi,i am very interested in getting a Papillon dog.I have read all the info on the internet i can possibly find.But what i really want,is some real owner experiences.The information that only someone who has spent a lot of time with the breed would know.
Things like-
Ease of training when they are pups?
How much energy they have,and how keen they are on walks?
How big are they?(can use another dog breed as a comparison)
How they cope with being left alone in the house for 4-5 hours?
Any other additional information would be brilliant! Thanks for taking the time to read my question.

Could You Give Me Some Information About Papillons?

Tell me what you knw about Papillons! Are they good dogs? I’ve heard they are harder to potty train than other dogs…is this true?
