During their early stages, puppies go through various behaviors and experiences as part of their development. These include teething, gradually adapting to their new environment, sleeping, engaging in playful chasing, seeking affection and cuddling, exhibiting hyperactive playfulness, and displaying a curious nature, always eager to explore new things. Toilet training may still be a work in progress, with occasional accidents occurring in the middle or sides of the space, while they tend to prefer pooping in corners. Their control over elimination improves over time.

Puppies have a hearty appetite and tend to eat quickly. They have a natural inclination to run around and discover objects in the yard that may not be entirely clean. When they begin venturing outside the house, they may exhibit excitement, sniffing everything in their path and exploring in a meandering manner rather than a straight line. Having two puppies can be enjoyable as they grow together, engaging in playful fights while also spending time running around as a pair. When fatigued, they peacefully rest together, without competitiveness, and when thirsty, they momentarily pause their play fights. They may occasionally compete for food, desiring what the other puppy has, even if it may not be logical.
