They provide no sources to back up the following which is contrary to the statistics provided by pretty much every other journalistic source.

It is not possible to calculate a bite rate for a breed or to compare rates between breeds because the data reported is often unreliable. This is because:

The breed of a biting dog is often not known or is reported inaccurately.
The actual number of bites that occur in a community is not known, especially if they don't result in serious injury.
The number of dogs of a particular breed or combination of breeds in a community is not known because it is rare for all dogs in a community to be licensed.
Statistics often do not consider multiple incidents caused by a single animal.
Breed popularity changes over time, making comparison of breed-specific bite rates unreliable. However a review of the research that attempts to quantify the relation between breed and bite risk finds the connection to be weak or absent, while responsible ownership variables such as socialization, neutering and proper containment of dogs are much more strongly indicated as important risk factors.
