Breyer introduced the Companion
Animal line in 1999. Scaled approximately to the Traditional scale, the line
began with the Welsh Corgi, Golden Retriever, Labrador Retriever, Jack
Russell Terrier, Silver Tabby and the Alpine Goat. The line was officially
discontinued in 2006 but these molds continue to appear
as part of play sets. I've added the small Owl models that were included
with the 2017
Holiday Horse as they most closely match the
scale of these molds.
