I remember when LBJ's Beagles used to do the same. A friend was THE WH vet that week ...chosen from vets at Walter Reed. NOT a very popular job. Anyway, one of the dogs obstructed and had to go to surgery. Of course the human Docs took over much to the relief of my friend... Dog died on the table.. Shows to go ya |
Humans do this too. In the South there were specific areas of a whitish clay that families used for dirt-eating to satisfy a "specific nutritional hunger" due to low levels of micro-nutrients in their food. These areas were not occupied as home or farm sites, but were defended against others.
