It has served him well and poorly in equal measures in various dog parks here—I am sure it would go both ways there, as well. Though he tends to like being around bigger dogs than smaller ones, so perhaps he would calm down with yours.
I still want to find a Dane to join him in the house, as I grew up with them (and Bichon Frise... the less said about that the better) but it’s a bit difficult with our residential council. It was quite the ordeal to get Watson approved, including practically buying off the chair (arranged a meeting with Yo-Yo Ma via a work acquaintance that puts on Art-Science discussions here; apparently it was like a Russian handshake).
Anyway, Mahrez, not a bad addition, yeah?
