What's that smell?

This is how I think this morning went down...

I let the dog out, something jumped into the hedge. Dog ran excitedly down the garden, I retreated indoors. 

Dog in the garden .... 'yo Fox, dude. Yeah you. Come piss on me my humans love it' 

Fox 'er yeah ok, like if you are sure'

Dog 'totally dude' 

Me inside on the bed trying to summon up energy for the day, dog comes up.

'erm what is that smell?' 

Pick up dog, sniff it, take it to husband. Husband picks up dog sniffs it 'why does it smell of fox pee' 

Dog thinks yeah see they love it.
