The vets sell it because Science Diet and Purina are the two major companies who actually give them their very limited education in nutrition and they also give out a lot of scholarships. Science Diet contains BHA, BHT and Ethioxin. Yorkies being so small could possibly be more rapidly affected, but many large dogs, many who did not eat canned, have become very ill or worse since this took place.
One thing the news is not sharing, Menu Foods actually knew they had a problem long before it was announced in the USA and they actually put out a release that said "not for distribution in the US. I guess they were worried about stock prices or something, but I find that unconsionable.
Thanks so much for this information. That is good to know. I'm going to give my yorkie some boiled chicken and rice tomorrow. Hopefully it will help. Hopefully he will eat it. It's kind of strange how I am hearing about other pets getting ill which have not eaten from the list. It seems too much of a coincidence. But, I pray it's just that.
