found when ectomorphy is dominant.The symmetry of social play in Canids has been previously studied, especially in wolves, free-ranging dogs, and within mixed-aged groups, however our study focused on symmetry and asymmetry within play interactions in two litters (14 puppies) of German Shepherd dogs (GSDs). At the age of 7 weeks, we evaluated 1287 dyadic interactions (litter 1 n = 339 interactions, litter 2 n = 948 interactions), and at the age of 9 weeks we evaluated 1255 dyadic interactions (litter 1 n = 433 interactions, litter 2 n = 822 interact
