#7 Training, daily routines to maintain appearance are time-consuming events. In addition, a long walk.
#8 Demanding coat.
Collies are long-haired and smooth-haired. Both require the daily brushing of the coat.
#9 Food and veterinary costs.
Such a smart pet requires remarkable expenses for the purchase of food. Only premium food will deign to eat collies. More precisely, they will eat anything, but they will remain healthy only with the right purchase. Cheap food will harm the body.
