Help pick my next book cover!

Help me out here, would you? I’m just about ready to publish the third book in my series, entitled The Dog Prince. Chapter one begins like this:

The May sunshine was already hot as it sparkled on the collection of frogs strewn across a rickety card table. I was running late and had forty miles to drive. The battery on my cell phone had died, so I couldn’t call and say I'd be late. I stopped to look at the frogs anyway.

And put into motion a chain of events that included mayhem and murder. I tell you, you just never know what will turn up at a good flea market.

I have several versions of the front cover that I’m considering. Of course I want it to be clear this is part of the series, so all the covers have some of the same elements as the first two books, which look like this:

And here are the covers I’m considering for book three. You can click on each image if you’d like to see it bigger (helps see the details!):

Version 1

Version 2

Version 3

Version 4

Version 5

The Dog Prince is very much a cozy mystery, laced with humor and featuring lots of dogs. I’d love to know which cover you like best. Feel free to make additional comments as well. Thanks so much for your help!
