received this from one of the Collie lists...I know some of you feed Canidae
Laurie

I don't know if anyone has been using this food but we have for over 2
 years and since opening a new bag it contained worms which we returned
 immediately and was given another bag. This bag had no worms but the
 color and size looked different. We didn't think too much of it and fed
 the 2 older shelties. Sam started with yellow smelly diarrhea and
scratch and biting his legs and feet. then he started vomiting
 indigestive food this made me start looking at what could be wrong with
 him he had no energy and was just not right. Molly only would eat part
of her food and walk away again not normal for her she was very gassy

 and her stools loose. She too itched and bit at her legs. Mia had no
 problems (she isn't on that food). My daughter went on line and
 discovered that Canidae has changed the food and there are allot of
 sick dogs out there.. We immediately stopped feeding the food and
 changed to another. Sam and Molly are getting better but still not up
 to their normal activities.. They were on this food about 2 weeks maybe.
 I am putting a web site here go to it if you use Canidae food and read
 the problems that have occurred. Please pass this on to anyother pet
 owners so they maybe informed.
