Median curves computed from ~89,000 healthy dogs aged 2–24 months in the open Salt et al. 2017 dataset (PLOS ONE, CC BY 4.0), grouped into PuppySize's five size classes.

Age % of adult weight Estimated weight
2 months 30% 5–6 lb
3 months 44.2% 7–9 lb
4 months 59.5% 9–12 lb
5 months 70.5% 11–14 lb
6 months 79.4% 12–16 lb
7 months 86.7% 13–17 lb
8 months 92.1% 14–18 lb
9 months 96.2% 14–19 lb
10 months 98.2% 15–20 lb
11 months 100% 15–20 lb
12 months 100% 15–20 lb

How confident is this estimate? Based on veterinary consensus; designer breeds vary more than purebreds. As a designer/mixed breed, expect a wider band than for a purebred; two puppies from the same litter can finish at different sizes.

About this breed's data: CORRECTED after verification: Daily Paws states 15-20 lb / 12-13 in; Hill's gives a wider 15-35 lb. (Prior 13 lb lower bound was not in either source.)
