The virus, which causes severe diarrhea that
kills baby pigs, thrives in cold weather, and declining immunity in the U.S. herd has raised the risk of another outbreak to the highest level since 2013, when pork prices soared to record highs, veterinarians said.
Of course Rotties and Pits are agressive, let a small animal that your Rott has never seen before walk onto your lawn, he'll rip it to shreds, my mom had a Rott when she was growing up and she said it would
kill their cats,
baby pigs, etc. none of the other dogs did but their rottie, they had many dogs back then too, so why didn't the other dogs do it??
