39,000 as far as we know but recently the Chinese destroyed 50,000 dogs there for some mysterious disease..
(excerpt) How many really died? It is now known that as many as 39,000 pets may have gotten sick or died. We know this because of the math done by one of the nation's largest veterinary hospital chains has made that astounding discovery. "Banfield, The Pet Hospital, said an analysis of its database, compiled from records collected by its more than 615 veterinary hospitals, suggests that three out of every 10,000 cats and dogs that ate the pet food contaminated with melamine developed kidney failure. There are an estimated 60 million dogs and 70 million cats in the United States, according to the American Veterinary Medical Association." (Andrew Bridges, AP - The real story...) During one three month period after contamination was reported this hospital chain saw a 30% increase in kidney failure for the 1 million dogs and cats it saw in that time period. The proof that the pet feed industry is not as concerned as they should be is in the number of recalled food. Only 1 per cent of all U.S. pet food has been recalled in spite of wide-spread use of Chinese wheat gluten in dog food. A larger recall would cost too much. There is still Chinese wheat glutton in pet food and animals are still being subjected to contamination if all the wheat glutton is not removed from the market. It just isn't the story it once was or never was. One veterinarian said "Nobody is ever going to know the truth." (end of excerpt) Full Article http://pnews.org/ArT/WaR/AnDy.shtml
