When I posted recently that I do run a pancreatic function test on a bitch before she is bred, I received some emails asking for more information. So I would not get anything incorrect, I asked my vet to respond to the questions asked and below is her response. As i stated in my original post Dr. Dunn did some very early work/studes on pancreatic function as it relates to German Shepherd Dogs specifically. She has a large clientele of GSDs including show dogs, companion dogs, rescue dogs, performance dogs and service dogs. Kay Springer www.showboatgsd.com Home of Multi BISS & Multi Group Winning GCh. Rohan's Reward TC,CGC,HT,RE,CDX,CHIC (h,e,h,t) DM Normal "Strider" 80 BOBs - #5 & #6 GSD 2009 Here is her response: I will test them young if I have significant worries about them (dropped pasterns, very thin, picky appetite, etc). I do find that some are normal when young and drop by 1-2 years, so I will retest later, and sometimes try to hold off if I can so I get a more accurate number. They need to be fasted to be accurate. I have seen the numbers normal when fed and dramatically low when fasted. The test is standardized for fasted, and many vets don't realize this. I treat anything under 10. The lab says 5, but Dr. Williams who developed the test and now is "semi-retired" says that is probably not a bad idea. Under 5 they are seriously ill from inability to digest food, but under 10 and they are still struggling - ie eating, but not able to absorb the nutrients, most is passing through to feed the bacteria. That is how I think it is related to toxic gut - there are lots of unabsorbed undigested nutrients inside the intestine and it is like a feast for bacteria.
