"?ANIMAL BEHAVIORISTS USED to think their bark was simply a way of getting attention. Now a new study suggests that individual dogs have specific barks with a range of meanings,? New Scientist magazine said on Wednesday.
Dogs usually use high-pitched single barks when they are separated from their owners and a lower, harsher superbark when strangers approach or the doorbell rings, according to Sophia Yin, an animal behaviorist at the university.
Playful woofs are high-pitched and unevenly spaced."
No shit. Anyone who's had a dog for 2 days knows that dogs have different barks for different situations.
Todays scientists are fucken morons. I'm starting to think the more we educate people the stupider they become.
