Your Puppy’s First Year 2025: Vet-Approved Month by Month Guide 🐶✨
By Dr. Duncan Houston BVSc
That tiny ball of fluff in your arms? They’re going to grow faster than you expect—and each month brings new milestones, challenges, and opportunities to shape your puppy into a confident, healthy adult dog.
I’m Dr. Duncan Houston, veterinarian and founder of Woopf. Here’s my monthbymonth guide to your puppy’s first year—what to expect, what to teach, and how to support them with the right gear and care at each stage.
🐶 Month 1–2: Transitioning From Litter to Life
- Most breeders and rescues release puppies between 8–10 weeks
- 🍼 Start of basic trust and human bonding
- 🛏️ Sleep 18–20 hours/day
- 🧠 Learning begins! Gentle exposure to new sounds, people, and touch
Vet Tip: Focus on comfort and gentle routines—not formal training yet.
Recommended Gear:
- Explorer Harness (size S) – Soft, secure for first walks
- Dual Pocket Dispenser – Early positive reinforcement
🐾 Month 3: Teething, Chewing & Socialization
- 🎓 Introduce sit, leash pressure, name recall
- 🦷 Puppy teething begins—chew toys are essential
- 🚶 Start leash walks with gentle guidance and rewards
Focus: Create positive experiences with strangers, surfaces, noise, travel.
Pro Gear Tips:
- Bungee Lead – Helps reduce puppy jerks & pulling on joints
🐕 Month 4: Puppy Energy Explosion
- ⚡ Energy peaks: Zoomies, jumping, chaos!
- 🎯 Start leash manners and crate comfort training
- 🛑 Behavior shaping begins—redirect instead of punish
Vet Tip: Most behavioral issues stem from lack of routine + structure at this age.
🐶 Month 5–6: Adolescence Begins
- 💥 Testing boundaries (selective listening begins)
- 💉 Time for final puppy vaccinations
- 🧠 Intelligence and memory improve—training sticks
This is where good gear is critical: consistency = security.
Bundle Suggestion:
- Explorer Harness (upgrade size if needed)
- Bungee Lead
🦴 Month 7–9: Full Teenager Mode
- 🧗 High risk of pulling, reactivity, and defiance
- 🏠 Reinforce crate training, calm greetings, and leash walking
- 👃 Introduce enrichment toys to redirect energy
Behavior Insight: Most dogs returned to shelters are in this age range. Gear + patience = success.
🐕🦺 Month 10–12: NearAdulthood
- 🎯 Learning stabilizes, physical growth slow
- 🏃 Longer walks, hikes, or runs now possible with vet clearance
- 📚 Now’s the time to reinforce everything you want to last into adulthood
Vet Tip: Don’t stop training! This is when skills “lock in.”
🎁 Your Puppy’s First Year Gear Checklist
- Explorer Harness – For all stages of development
- Bungee Lead – Prevent injury from pulling while learning
- Dual Pocket Dispenser – Rewards + poop bags in one
