Abstract
Summary
Newborn puppies have greater glucose titration splay than do older dogs, with a resultant lower plasma glucose threshold. The greater splay coincides with continuing nephrogenesis in the newborn puppy and may be explained by increased glomerulotubular nephron heterogeneity. A linear relationship between T G and GFR at saturating loads applies to the newborn as well as to the adult dog. Tubular function appears to be more depressed than glomerular function in the young puppy.
