I personally have no problem with the YTCA collecting stickers from Purina bags. Purina gives them money for the stickers collected. I think half of it goes to the CHF, and half to the YTCA. Purina has many varieties, and some of the premium blends don't sound that bad to me, for example, the lamb and rice. I don't think we understand canine nutrition any better than we understand human nutrition at this point. I know some people think all the facts are in, but there still is an awful lot of disagreement among the experts. However, I don't feel that this means that they are endorsing Purina, but only if someone were feeding their dog this anyway, could they please send in the stickers from the bags? I should be clear about this, you actually sign up at Purina, and list the Yorkshire Terrier as the breed, don't send stickers to the YTCA, but to Purina. Here's a link to some of the donations they YTCA has made.
