The statement "There were puppies smaller than dogs" is logically sound, as puppies are, by definition, young dogs and therefore smaller than adult dogs.

Regarding the interaction between wild dogs and puppies, the following can be stated:

• Social Structure: Wild dogs, such as African wild dogs or wolves, typically live in packs with complex social structures.
• Pup Care: Within these packs, the adults generally care for the puppies. Pups are integral to the pack's future, ensuring the continuation of the pack.
• Protective Behavior: Adult dogs are very protective of puppies within their pack, and will defend them from threats.
• Friendship: Defining "friendship" in animal terms is complex, but it can be stated that adult wild dogs exhibit behaviors indicative of care, protection, and tolerance toward puppies within their social group.

Therefore, in the context of a wild dog pack, adult dogs generally exhibit behaviors associated with taking care of puppies.
