July 16, 1974 .-Jr. C r arles E. Kas...er 411 So u l ., .ircn Street Berwicn, ,e.. syiva. ta L86u3 Bear Mr. Kasiu.er: Your problem wit.- t e litter of pups suspected of ravin., ieaa puisoni,._ is a bit difficult for me to deal wita bn t..e iaiorr.ati waic*. you t.ave Su.-ulii i lo o, .si. ce I ow absolutely nothin, about eitaer your veterinaria., or the Laiare bauoratorles. Let me say tnat I Save not tne fai test idea of ..o your veteri :arian .manes a presun.,,tive aiaqrosis of lead poison in;; i i tne case of very y o u n . eo^s. I am sure tuat very few practitioners of veterinarian medicine can make, suca a diagnosis or nave a.y lea at ali as to tne clinical ..attern of the disease iu pups. Consequently, I j t skeptical. Moreover, the analysis of various aterais for lea- is a toucny matter, wuile ail sue., materials as food in e* eral, and, especially, .asat-contanning foou for dob i, all <>f sucu contain lead, a..d ti.e quantity of ieaa qientioned i-n t.ns case is not, in any sense, remarkable. Consequently, ]/ ooubt^ very much li t.-ie &o;i iooci has any responsibility for oeinr able to iuctuce lead poisoni..p in uobs . Unfortunate iy, I nave rad little experience witn cicgs, and none with ps, and so I ca.-r.ot be certain that tne quantity referred to is i.'.si,;ni fleant. I would, tnereiore, discontinue f e e d i,, it ana resort to tne* . use .of ,,.ilk (of ..ooa quality) lor a ti ,e. ti. do I .,-ve s; v-.-.t'n sc -....biouSiy oi the v<_ t a.d tre laborator- to which you r t n e m a , I wo .In s .. pest that, tne vet write to tie ana tei.l .me of nis experience ana s.-eak of tne analytical ,roctdi.re employed by tne Laboratory. He mi,at ii ue wis.ics tell me somethin, about tne Laboratory, of wnic.. I nave not reare previously. It would be weil if you should look carefully into any other source of lead, seen as painteu objects in t..e environment of the *.u p s . I shall be lad to assist you in any w iy I can, but I believe you will under stand me, in that I nave pointed out to you tnat you nave no sound evidence tiiat your pups have or are threatened oy lt-xti poisoning. Corciaily yours, u o: wb Robert v. Hehoe, M.D. Professor" Emeritus of Occupational Medicine
