The breed of dog in the opening scene of the pilot is a Belgian Malinois, commonly misconstrued as German Shepherds.
About half way through the episode, the character doing gardening says "did you see that? All the toads". Then it cuts to a scene of bull frogs. The CGI leading up to this could be toads, but even subtitles say "frogs croaking". Although with some similarities frogs and toads are different and identifiable.
