Photos of new puppy, Jessica, the day after we received her: age 8 weeks 1 day.
Jessica 9 weeks and 1 day. Ben got along with her okay. When she became a nuisance he'd move away.
Jessica at 10 weeks
Duffy didn't initially like her, but here he is lying down somewhat close to her. He seems to like her on hikes but not so much at home.
Jessica is 11 weeks old here and surprisingly to me, Duffy initiated play with her.
Evidence that Jessica does sometimes use the backyard for wetting purposes -- as opposed to my study.
In this sequence Ben seems disinterested in what Jessica and Duffy are doing, but he eventually gives himself away.
