We do love our pets (hello, Lilly). The title of the Carnegie Center’s latest exhibition, “Biophilia Life; or, My Best Friend Has Four Legs and a Tail,” needs a little explaining. “Biophilia” is Latin for loving life. The subtitle tells us exactly whose lives we are loving. With over 62 percent of Americans owning a pet — that’s a lot of bonding — artists such as Gaela Erwin, Carlos Gamez de Francisco and William Wegman show us what this pet love looks like. The public reception is on Dec. 14 from 6 to 8 p.m. (the members-only curator’s talk is at 5:30 p.m.).
