Other factors that could contribute to slower walks or shorter walks include dog aggressiveness toward other dogs (Řezáč, Viziová, Dobešová, Havlíček, & Pospíšilová, 2011),
friendly interactions with other dogs (e.g., meet and greet; Westgarth et al., 2010), playful interactions with the owner during walks (Rooney, Bradshaw, & Robinson, 2000), and dog age (Rooney et al.).
