In Search of a Friend

I've observed that Bella responds better to calm adult dogs than she does to puppies.  She doesn't want a boisterous dog harassing her, but rather a dog that gives her space.  Several people who know a lot about dogs have suggested that a male dog would be a wiser choice than a female for Bella.  So that narrows the search to a calm, adult, male dog.  A gentle boy who understands that a girl needs to make her own choices.   This lovely lady might enjoy a companion.   Is there a dating site for dogs?  How would the ad read?  Wanted: a kindly, low key kind of guy who has lived a little, but still has a lot to give.  No one pushy, or rambunctious, just a goodly fellow who enjoys long walks by the lake, a nice chew, and maybe, if things work out, side by side doggie beds.
