I am seriously p*ssed off. Harvey Levin, who hosts some celebrity "news" show (which seems to consist of videos of people walking), displayed his complete lack of knowledge about dogs by muttering something about "pit bulls" and an enzyme in their brains. His built-in peanut gallery nod their heads like bobble dolls in the backs of cars.
More media crapola we have to deal with. I don't know if celebrity video shows qualify as mainstream.
Harv, Harv, Harv. Show me the scientific proof to back up your claim about "enzymes" in a "pit bull" brain.
Because neither exists. Neither the enzyme nor any scientific proof.
Harv, get informed. This is a much bigger battle than you probably know.
