They don't half guess, i took my staff the vet the other day cause shes has skin conditions and she said it may be the additives in the foods, so i told her i give my "other" dog raw meat, veg, and SA37 and bits of other things and the "other" dogs healthy, so i would try my staff on that, to be told, theres not enough extras in there that dogs need Well make ye feckin mind up additives or no additives.
PS: you vets probably an anti
either an anti or a thick f*ck.....mind you she was a woman so that says it all
