Dogs start off needing (as VERY young pups) 2X the amount that an adult dog of that same weight would need. As they approach 1 year age, this declines to 1X (or the same as) the adult dog. But, since most Labrador puppies have not read the nutrition chapters in the , they keep insisting on more and more. The typical Lab is an illiterate glutton.

From inspection of the growth components in and the dendrogram in , we see that the separation in the cluster analysis occurs principally at adult maximum body weight, which drops abruptly from 43.3 to 28.1 kg between the Newfoundland and Labrador Retriever breeds. However, the time to reach 50% of maximum body weight also contributes to the separation between breeds, unlike the early growth rate, which is very variable and less discriminatory.

However, the data also suggest that additional differences in growth patterns may exist in breeds of similar size. For example, cluster analysis separated the Newfoundlands from the other giant breeds and distinguished Labrador Retrievers from English Springer Spaniels and Beagles in the medium- and large-sized categories. Because cluster analysis uses a combination of parameters to determine dissimilarity between groups, it is not possible to determine from the present data why these similar-sized breeds were separated. However, the Newfoundlands had a lower adult weight (a) and higher exponential growth rate (1/b) compared with the other giant breeds. In addition, sex-ratio differences for the different breed groups studied () complicate interpretation, because males and females may have different growth patterns. Sex differences were reported in previous studies (,) with males taking longer to reach adulthood than females. Whether this sex effect occurs in all breeds or has any practical impact remains to be seen, but it may explain some of the differences observed here including the separation of Cocker Spaniels from other small-sized breeds (sex-specific data not shown). These breed-specific differences in growth pattern warrant additional study.
