Although the importance of DHA and ARA in neonatal development has only recently been recognized, linoleic acid (18:2 n-6) has long been known to be an essential fatty acid with important roles in skin integrity among other body systems. Linoleic acid competes for the same enzymes as ALA, and the downstream long-chain n-6 fatty acids such as ARA are considered to promote the production of more inflammatory end products (ie, eicosanoids) than are the n-3 family. Thus, even though there is an essential requirement for linoleic acid, high amounts are thought to drive excessive inflammation, particularly in the absence of appropriate amounts of n-3 fatty acids. Two of the milk replacers had linoleic concentrations far in excess of that found in the dog milk, and some had n-6:n-3 fatty acid ratios as much as 5-fold that of dog milk. Both of these factors could potentially contribute to a greater propensity for inflammation in puppies. Interestingly, 2 dog milk samples also contained linoleic acid concentrations that were much less than the NRC RA. Previous studies that have reported linoleic acid concentrations in dog milk have not provided adequate information to allow for a direct comparison with the values obtained in this study. An NRC MR for growing animals is not available for linoleic acid; however, in previous studies,, weaned puppies had dermatologic signs consistent with linoleic acid deficiency after 2 to 3 months if not fed diets containing at least 2% linoleic acid (approx 2.2 g/1,000 kcal of metabolizable energy). Because most puppies are introduced to balanced diets containing at least 2.9 g of linoleic acid/1,000 kcal (the Association of American Feed Control Officials minimum recommended concentration for growth and reproduction) at around 4 weeks of age and are typically completely weaned after 6 to 8 weeks, it may be that dog milk does not require such high concentrations to sustain appropriate puppy growth and skin condition in the short period of time that puppies rely only on dog milk for nutrition. Alternatively, it may also be that younger puppies have lower linoleic acid needs than puppies after weaning or that the concentration of other n-6 fatty acids in dog milk (eg, ARA) has a sparing effect on linoleic acid. Finally, the possibility of incomplete recovery of linoleic acid from samples or different processing methods could also not be entirely ruled out to explain the discrepancy between linoleic concentrations in dog milk versus the NRC requirements.
My husband and I have two of our own dogs and we are also taking care of my parent’s dog until they get a place that allows pets. As I was searching the Internet for pet insurance coverage, since we were talking about getting it on all three dogs, I found your awesome website with the comparison chart.
