Dog sociability

There's a lot of myths floating around that dogs want to be friends, and should be friends, with any and all other dogs. This is simply just not the case. And I say this as someone who used to own a dog walking and dog daycare business!
With my current five dogs:
Dave would prefer to be the only dog on the planet.
Freya & Grace are dog tolerant, but only when they are all on the same side of the fence Polly & Tigg are dog selective.
Where does your dog fit in the spectrum?
