Early most weekday mornings you'll find Cooper running around at Runyon Canyon with his 'Lab Pack'.
He has friends in every flavour, chocolate, black and on some days yellow Labradors too.
The best thing about our pup being able to play with other Labradors is that they play exactly the same and seem to know how to do the rough and tumble without ever going too far (that is not turning aggressive like some other dogs) and all have so much energy to expend.
Cooper's pals include Woody, a chocolate Labrador, who Cooper tends to roughhouse with at the beginning and end of his walk.
Most other times he's the shadow to Tikka, the black Labarador, and the tennis balls she's equally obsessed with.
Rounding out the photogenic pack is new addition to the troupe, Sienna, another slightly smaller chocolate Labrador.
Some days there are also two more yellow Labradors, Finn and Riley, to join in the fun, but not today.
As you can imagine they make quite a sight frolicking around the Runyon Canyon trail.
There's always lots of smiles around when the playing pack goes by (although sometimes some concern on the steeper slopes too).
In between the playing there's always time for water breaks and they always know their usual shaded pit-stops (although that may have something to do with treat time).
But it's not long before it's back to the fun and games, wherever their adventures may take them (usually in bushes, up and down slopes and in puddles of dirty water).
Nearing the end of the walk and there's nothing like satisfied, tired Labradors to make you feel like you've done a good job exercising them and the thought you'll get a few hours break whilst they sleep.
As you can see, there's a reason why Cooper gets so excited about going to Runyon Canyon...
