Query: A complete waste...

I expected better from Ragnar Benson. This book is tiny (only slightly bigger than the picture on this site) and very, very short. For $12 I expected something much more substantial. I contains no useful tables or charts, no dosage suggestions... nothing. Virtually everything in it is basically common sense information that any reasonable person should be able to figure out by simply looking at the labels of various veterinary medicines. Save your money, and your time. I'll be returning this one.
