* Growth Rates Vary: Both Labrador Retrievers and German Shepherds have similar growth curves, reaching maturity around 18-24 months. However, individual growth rates can vary based on factors like genetics, diet, and overall health.
* Average Size: Labrador Retrievers typically reach their full height earlier than German Shepherds, but German Shepherds tend to be larger overall. This means a German Shepherd puppy might be smaller than a Labrador Retriever puppy for a period, but could ultimately grow larger.
* Growth Spurts: Both breeds have periods of rapid growth (growth spurts). During these spurts, one breed might appear to grow faster than the other, but this is just temporary.
In conclusion: It's difficult to say definitively which breed grows faster. Both Labrador Retrievers and German Shepherds have similar growth patterns, and individual variations are common. If you're interested in specific growth rates for your puppy, it's best to consult with your veterinarian.
