[quote]…There is no national system in the United States for tallying reports of dog bites. The often-repeated numbers that inspired some to declare a dog bite “epidemic” were estimated on the basis of a telephone survey conducted in 1994. From among the 5,328 persons who responded to this survey, interviewers obtained reports of 196 dog bites within the previous 12 months. (Only 38 of those sought medical attention).*…

Alarmists quote the numbers extrapolated from this 14-year-old telephone survey as evidence that dogs are a growing threat.

However, communities across the country report the good, less publicized news that actual (not estimated) reports of dog bites are decreasing, and have been for years.[/quote]

And both the CDC and AVMA have released statements re the belief that some people have that some dogs are more likely to bite.

Too bad education wouldn`t occur year round instead of just 1 week a year.
That would reduce bites even further.
