DENVER (KCNC/CBS 4) - Lawmakers are looking to put an end to cops killing dogs.

They say police need more training when they come into contact with canines.

A new bill would require all law enforcement in Colorado to take a two hour training course and annual follow-up in hopes to protect dogs from unnecessary violence.

Concerned over the number of dogs shot and killed by police recently, Colorado Senator David Balmer is spearheading the bill. According Balmer, it is the first of its kind in the nation.

The bill's final draft is expected to be introduced later this week.
