The Kaggle Animal Bites dataset, loaded and parsed as CSV.

Question on the dataset: a large number of the rows in this dataset are missing data about the vaccination date or number of years. Would a dataset consisting of only the bites where this information is known be more useful for analysis, or would it be too small of a subset?

Possible tasks on the dataset: determining aggression in various animals and dog breeds to help breeders understand desirable or undesirable traits
