Btw, if you want an opinion from a VET who really advocates for our dog's best health - and not her bottom line - you should check out this Vet's (Dr. Terifaj) blog:
DOG-Breath — “An outspoken commentary of ideas, healthy insights, and occasional rants that will bust your dogma!”
She will tell you the the truth about nutrition, vaccines, and highlight some of the common mistruths found in the vetrinary field. She is WONDERFUL.
