Sheepadoodles typically stop growing and reach their full adult size between 9 to 18 months of age. The exact age at which a Sheepadoodle reaches its full maturity and stops growing depends significantly on its size variety, ranging from Toy Sheepadoodles maturing earlier to Standard Sheepadoodles requiring more time.
Sheepadoodle Growth Stages by Type
The growth timeline for Sheepadoodles varies based on whether they are Toy, Miniature, Standard, or Giant. While they may reach their "mature period" for rapid growth earlier, their "full adultness" represents when their skeletal development is complete, and they are no longer expected to grow taller.
Here’s a breakdown of when different types of Sheepadoodles reach their full adult size:
| Type of Sheepadoodle | Mature Period (Rapid Growth Slows) | Full Adultness (Stop Growing) |
|---|---|---|
| Toy Sheepadoodle | 3.5 to 5 Months | 9 to 11 Months |
| Miniature Sheepadoodle | 3.5 to 5 Months | 9 to 13 Months |
| Standard Sheepadoodle | 5 to 6 Months | 12 to 18 Months |
| Giant Sheepadoodle | 5 to 6 Months | 12 to 16 Months |
As the table illustrates, smaller Sheepadoodle varieties, such as the Toy and Miniature, generally reach their final size earlier than their larger counterparts. Standard and Giant Sheepadoodles have a longer growth phase, often continuing to grow in height and fill out in body mass up to 16 or 18 months of age.
Understanding Growth Milestones
- Rapid Growth Phase: During their initial "mature period," Sheepadoodles experience their most rapid growth spurts. This is when they gain significant height and weight quickly.
- Slowing Growth: After this initial phase, growth begins to slow down, but they continue to develop.
- Full Adultness: Reaching "full adultness" signifies that their bones have fused, and they have achieved their maximum genetic height. While they may continue to fill out in muscle mass and weight slightly after this point, their skeletal growth is complete.
Monitoring your Sheepadoodle's growth with regular vet check-ups can help ensure they are developing at a healthy rate.
