Minnie is still here and has almost doubled her weight in the last two weeks, now weighing in at a whopping <g> 8 oz.  She is still behind the others with a much lower energy level and to get from point A to point B she takes the most efficient route - usually by skittering under the bellies of her littermates.  She now reaches into the bowl to eat - instead of climbing in and sitting in the middle of it.  She has also learned to lick better and laps some water from a custard cup if I hold it.  She still prefers, though, to lick from a syringe (with the needle removed!) instead of trying to put the whole thing in her mouth and trying to suck it like a bottle (I am afraid to leave a water bowl down that she can reach for fear she will try to crawl in it and would drown).  Her coordination is much better and she rarely falls down any longer and does give little wags with her tail.  She was large enough to get some blood samples from last week - but we still don't know what is causing her slow development.  The kidney function tests show that while her kidney function is low, they are functioning at the edge of normal.  A thyroid panel has ruled out problems there - all the results were exactly where they should be. We'll be running the tests again at the end of next month to compare the results and see if anything "interesting" turns up.  At the same time, we will run kidney function tests and basic blood work on some of the other pups as well to be sure all is as well with them as it appears and to make sure their systems will be able to handle their first vaccinations.
