Done growing, by size group
Small dogs finish growing early and giant dogs keep going for up to two years. The bigger the grown dog, the longer it takes to get there.
| Size group | Grown weight | Examples | Done growing |
|---|---|---|---|
| Toy | Under 12 lb | Chihuahua, Yorkshire terrier, Pomeranian | 9 to 12 months |
| Small | 12 to 25 lb | French bulldog, Cavalier King Charles spaniel, Boston terrier | 10 to 12 months |
| Medium | 25 to 50 lb | Border collie, Bulldog, Australian cattle dog | 12 to 15 months |
| Large | 50 to 90 lb | Labrador retriever, Golden retriever, German shepherd | 12 to 18 months |
| Giant | Over 90 lb | Great Dane, Mastiff, Saint Bernard | 18 to 24 months |
For example, a large-breed puppy of 30 lb at 16 weeks is about 42% of its grown weight. Grown, it will likely weigh 55 to 88 lb, and it will likely get there at 12 to 18 months.
