The New Castle County Police Department has four new faces on their team, except these belong to four-legged friends. 

In a Facebook post, New Castle County Police announced that the latest batch of K-9s have graduated after completing their training. 

The Canine Unit started in 1986 with now-retired officer Stan Downward and a bloodhound named Jesse, according the New Castle County Police Department.  

Now, there are 14 teams involved in search and patrol work, and some are trained in explosives detections.  

Training for the unit is six months long, with each dog being cross-trained to perform searches for missing persons, contraband and routine patrol work.

Each patrol squad has a K-9 team assigned to it. 

New Castle County Police sent well wishes to each new dog for their first day of patrol, and plenty of commenters followed suit to make sure the newest class of K-9s received a warm welcome in advance of serving and protecting Delaware.  

“Way to go! CONGRATULATIONS to all the grads! God bless and protect all the two and four-legged officers out there,” one user commented. 

“Congratulations to all these precious beautiful pups. Pray that you wall will be safe out there going forward,” said another. 

“I’m in love with all of them! They are all so proud, look at these kissable proud faces!” said a user.

One Facebook dubbed the new squad on the block as “paw patrol.” Others thanked the newest K-9s, and their partners, for their service.  

“Congratulations on all of your hard work to get here! Prayers to always come home safely. Thank you ALL for your service,” said a commenter. 

Along with all the support already shown to the newest members on staff, we hope their first paycheck includes a hefty sum of dog treats and chew toys.
