🥦 Nutrition: Feeding for Growth

Why Puppies Need Specialized Diets

• Puppies require more protein, fat, calcium, phosphorus, vitamins, and calories than adults :contentReference[oaicite:2]{index=2}.
• Look for an AAFCO statement: “complete & balanced for growth” or “all life stages (growth ≥70 lb adult).”

When to Switch to Adult Food

Feed growth diets until about 80% of adult size: ~12 months for small/medium breeds, and ~18–24 months for large/giant breeds :contentReference[oaicite:3]{index=3}.

Large‑Breed Puppy Nutrition

These diets have lower calories, calcium (0.8–1.2% DM), and phosphorus to prevent rapid growth and orthopedic issues :contentReference[oaicite:4]{index=4}.

Adult Food Isn’t the Answer

Switching to adult dog food at six months can unbalance calcium/phosphorus or increase calories :contentReference[oaicite:5]{index=5}.

Manage Body Condition

Adjust portions to maintain a lean score (BCS 4/9). Even large-breed growth diets can promote weight gain if free-fed :contentReference[oaicite:6]{index=6}.

Homemade Diets Require Experts

DIY puppy meals often lack essential nutrients. Consult a board-certified pet nutritionist before hand-preparing food :contentReference[oaicite:7]{index=7}.

🏃 Exercise: Building Strong Bodies Safely

Growth Plates & Risk of Injury

Forced or repetitive exercise before growth plate closure can cause developmental damage :contentReference[oaicite:8]{index=8}.

When Growth Plates Close

Small breeds: ~6–12 months | Large breeds: ~12–16 months | Giants: ~18–24 months :contentReference[oaicite:9]{index=9}.

What Counts as Forced Exercise?

Any sustained activity beyond puppy’s normal play: jogging, fetch, long hikes, repeated jumping :contentReference[oaicite:10]{index=10}.

Safe Activities for Puppies

• Short, leash walks—non-demanding
• Free play with similar-aged pups
• Swimming—low joint stress :contentReference[oaicite:11]{index=11}
• Mental enrichment—sniffing, training, puzzles

Begin Low-Impact Training Early

Around 4–6 mo., introduce core and coordination exercises: backing up, pivoting, supervised stair use, gentle strength work—not jumps :contentReference[oaicite:12]{index=12}.

Delayed Intensity Until Growth Plates Close

Vigorous exercise—jogs, sports, agility—should wait until bone maturity (~12–16 mo large breeds, later for giants) :contentReference[oaicite:13]{index=13}.

🧠 Tracking Your Puppy’s Progress

Monitor weight, body condition, appetite, energy, stool, and growth monthly. Prompt vet reviews for any concerns.
