Geoffrey is 15 mos old now. We knew shortly after we got him at 10 weeks of age that Mr. Social Butterfly needed a buddy. We put in a reservation with his breeder who recommended that he be about a year old before he got a little sister.
We brought 10 week-old Gracie home Sunday. She is a half-sister to Geoff (same dad). Geoffrey loves to rough and tumble. A bit much for Gracie right now. They like each other, tails are wagging and they give each other lots of kisses. Gracie is far more laid back than Geoff. They had several visits at the breeder along with her 3 female litter-mates to see who clicked with Geoff. He was too much for 2 of them, the third was a carbon copy of Geoffrey personality-wise. Gracie didn't take any guff out of him, but reacted much more calmly than her higher energy sister.
We are limiting direct contact. When outside, we put Geoffrey outside the dog run and Gracie inside. They run "together" with the wire fence inbetween giving kisses through the mesh. Geoff's crate is right next to hers with a few inches inbetween. When she is in her crate during the day, Geoff is loose in the kitchen. Direct contact is with us right there to intervene when Geoff gets too excited, hand in collar talking to him quietly. We don't leave her outside unsupervised either, just to be clear.
Are we doing this right? Are there other things we can do to be sure everybody gets enough attention?
