1. Socialisation
Naturally, dogs are sociable animals. In the wild they travel in packs for that very reason. In the modern domestic home, while they love their human families to bits, they also enjoy mixing with their own kind.
Coming to day care is therefore not always out of necessity, for example because their owners are out all day at work. It’s also because of the fun they have frolicking with their four-legged friends and in turn learning new and important doggy social skills.
