Growth Velocity Note
Yorkies gain the majority of their weight in the first 16 weeks of life.
Veterinary Feeding Guidance:
Feed micro-kibble specially formulated for toy mouths to ensure adequate caloric intake and prevent hypoglycemia.
Yorkshire Terrier Week-by-Week Weight Milestones
Reference data for healthy Yorkshire Terrier puppies based on veterinary pediatric percentiles.
| Puppy Age | Expected Weight (lbs) | Expected Weight (kg) | Developmental Milestone |
|---|---|---|---|
| 8 Weeks (2 mo) | 1.0–2.2 lbs | 0.5–1.0 kg | Delicate juvenile transition |
| 12 Weeks (3 mo) | 2.0–3.8 lbs | 0.9–1.7 kg | ~50% adult weight reached |
| 16 Weeks (4 mo) | 2.8–5.0 lbs | 1.3–2.3 kg | ~70% mature weight |
| 24 Weeks (6 mo) | 3.5–6.2 lbs | 1.6–2.8 kg | Skeletal growth completion |
| 36 Weeks (8 mo) | 4.0–7.0 lbs | 1.8–3.2 kg | Full adult weight |

When Do Yorkshire Terrier Growth Plates Close?
For the Yorkshire Terrier (toy breed classification), epiphyseal growth plates typically close between 8–9 months. Until these cartilaginous zones calcify into solid bone, the skeletal structure is particularly vulnerable to impact trauma.
- Avoid repetitive high-impact jumping (such as off tall beds or out of SUVs).
- Postpone intense agility hurdles or forced running on concrete until growth plate fusion is complete.
- Maintain lean body condition: excess puppy fat places unnecessary biomechanical torque on immature ligaments.
Nutrition & Weight Maintenance
Caloric demand peaks between 8 and 16 weeks, during which puppies require up to twice the calories per pound of body weight compared to adult dogs.
Feed micro-kibble specially formulated for toy mouths to ensure adequate caloric intake and prevent hypoglycemia. Weigh your puppy bi-weekly and adjust portions according to their body condition score (BCS) rather than bag recommendations alone.
