Visiting dog is content, although seems to have a look of pining for home at times. Has found an exercise ball to hump instead of the children’s legs.
Had to explain what humping means to older child. Older child went white, then green, and then complained that his leg felt funny.
Resident dog has spent more time downstairs, though still refuses to interact with visiting dog. At one point, resident dog was seen sniffing the hind quarters of visiting dog. When visiting dog turned around, resident dog quickly trotted away and whistled nervously.
