I was going to bed when suddenly your genitive plural (I would say plural genitive) killed the sleeping mode in me. I had to check. What genitive form is there in your sentence ?
It is most appropriate that those who profess to believe without question the barks of the dogs are evidence, when the expert clearly states that they are not, should post with such an ingrained cynicism on other issues.
In order that you do not yourself bring discredit upon your claim to be a grammarian, I would ask that you reconsider the content of the post you have made.
Firstly if you were to insist upon the phrase "plural genitive" rather than the correct "genitive plural" then you would be going somewhat against the grain and showing a lack of fluency in English as the normal usage is the form I have used.
Secondly your inability to apparently recognise the genitive plural phrase within the sentence is quite incredible as it is in the prepositional (partitive) construction common in both French and Portuguese rather than the apostrophe 's' construction which is also used in English. For you not to recognise that "the barks of the dogs" is a partitive genitive construction is quite shocking for one who supposedly prides herself on her knowledge of grammar particularly in Romance languages where that construction is so widely used.
