Are matching dog PJs a good thing?

[Catherine]

I bet Misty really appreciated that coat when it was cold. She looked good in that colour. I am sure Misty was able to make anything she wore look good.

 Some dogs do need a coat when it is cold. The dogs in the pictures had thick fluffy coats and they would be too warm. If people paid a lot for matching dog PJs they would want to see their dog in them at least on Christmas day.  Why couldn't they settle for a little bit of matching material in a dog suitable accessory. 
They are doing it for themselves and not for the dog.

(I am not sure all the children are too happy about the matching PJs either.)
