Tollers have the capacity to be very social dogs as long as they are sufficiently socialized early on in life. While Tollers are energetic and outgoing around their owners and family, their cautious nature makes them reserved around strangers. Exposure to new people, locations, smells, and sights are crucial to the healthy development of the Toller breed. They tend to get along well with other dogs, however, they have a strong prey drive and may chase after cats or other small animals. Their prey drive can be avoided if cats, for example, are introduced early on in a Toller's life. Failure to properly socialize Tollers at a young age may result in aggressive, destructive, or timid behaviour in maturity.
