Nice, it makes you happy to see them having so much fun.
Our pup likes playing with long grass, sticks and branches and my tools, n nut's and bolts just as much as playing with her toys that we bought her.
And i wish our yard was as big as yours.
It's good to finally have a dog that likes water, our last 2 staffy's didn't really like it.
I'd get the hose out to water the garden or wash a car and they'd both be off and hiding
Our pup is growing fast, she's put on about 3.5kgs now, and is about 150mm longer/slightly taller.
She loves water too, if i turn the tap on above the dogs water bucket Missy loves to bite at the water, and snaps at it as it overflows.
It's been pretty hot here the last few days and the boys have been out on the trampoline with the mist sprays going.
Missy gets excited watching them, jumping and barking, so we tried her out in there with the kids a few times.
She run's around and around playing, bouncing with them, licking up the water on the mat and the mesh sides.
It's pretty funny to watch, especially when she has a burst of energy and does her flat out run around the yard too etc.
