I h~d a litter of Greet Dane pups that the Vet said was showing clinical signs of lead poisoning. The Vet attempted to locate the source of the problem. The only thing the Vet and I even suspect -t this point W'as anew bag of "Thrivetts" deg food which the litter had been recently introduced to. D-lare Labs analyzed the dog food ^nd found it to have a lead content of 0.4 ppm. The Vet or I have been unable to locate any information on the acceptable amount of lead in feedstuffs". We would appreciate -my information you mignt hove on this subject or ~ny suggestions ^s to where to find the inform: tion. Therk you ,7 Charles E.
