L-Girl's already posted an extensive write-up of the visit, so I'm not going to go into a lot of detail, but here are some photos:
Denim jumped right into the fun.
Cobalt and Tala are, of course, good friends now. Denim was a little wary.
Tala and Cobalt got right into the chase games.
All four together.
Cody, it turns out, loves little dogs, and spent the whole time following Denim around.
Cobalt would retrieve the ball, Tala and Denim would chase Cobalt, and Cody would chase Denim.
Denim just couldn't get away!
She found Cody's attention a little overwhelming at times.
Denim ended up a little mussed from Cody constantly slurping her head.
She tried retreating up onto a snow pile, but it wasn't tall enough to get away.
Meanwhile, Tala was fixated on Cobalt.
Eventually, Denim discovered that she could fit between the slats in the fence, and visited the neighbour's yard. Fortunately, her recall is good, and she returned on command -- but moments later, Cobalt went through, then Denim again, and we decided to move indoors where we wouldn't lose track of the dogs.
