I am sure tout very few practitioners of veterinarian medicine can snake, sucn a diagnosis or nave d.y iuea at all as to tne clinical ...at tern of the disease i.. pups. Consequently, I a>r skeptical. Moreover, the analysis of various naterials for lea- is a toueny matter, wuile all sue., materials as food in e. eral, and, especially, .seat-containing fooa for do-0s, uii of sue.- contain lead, a..d ti.e quantity of ieaa mentioned i-n tms case is not, in any sense, remarkable. Consequently, T/ aou'oti vary much li t.-ie cog iooc has any responsibility for being able to iua-.ee lead poisoning in cogs. Unfortunately, I nave uad little experience witn cogs, and nohe witn ,....ps, and so I cu.-r.ot be certain that tne quantity referred to is insignificant. I won la, tnereiore, discontinue feeaiu,. it ana resort to tne use .of .-..ilk (of ,.ooa quality) lor u ti ,-e. ft. Co I ......re .on sc -....biousiy ol tne vet at.d t.-e ubontor" to which you rcncrrcci, I wo-.. In s .. post chat. tn.e vet write to me ana tei.l za of nis experience ana s.-eax of tne analytical t rocedure employed by tne Laboratory. He mi^nt ii ne wishes tel l me somethin*, about tne Laboratory, of wnic.. I nave not ueard Krevio'.sly. It would be weii if you should look carefully into any other source of lead, seen as pain tea objects in t..e environment of the pups. I shall be glad to assist you i', any w ty I can, hut I believe you will under stand me, iu that I nave pointed out to you tuat you nave no sound evidence that your pups have or are threatened uy it-ua poisoning.
