Following that link crashed my browser so I went to the sit and found the article. It is very interesting. I'll include it in this post for those who want to read it. This is a good point of discussion.[br] [file={e_FILE}public/1309873933_2_FT79823_livestockguardiandogsk.pdf]livestockguardiandogsk.pdf[/file] I followed the reference to the USDA website and found the the AIB has been updated in 1999 and is not AIB 588. It has some very good points and in particular, I am going to use the guidance starting on page 11 with my next pup. Will let you know how it turns out. I added the updated bulletin to the [url=http://molosserdogs.com/downloads126.html]download section[/url]. It is a very good resource.
