Dogs aren’t just amazing pets and companions — they are so helpful in many other roles. Since dogs have excellent senses of smell and incredible instincts, we use them to help us across many professions.

Dogs are known to be talented and impressive police K-9s, service dogs for people with disabilities, guide dogs, military dogs, fire dogs — the list goes on.

However, even though these pups are born with incredible instincts, they still need a fair amount of training — these professional dogs all have to start somewhere, right?

It’s the first day on the job for these 30 pups — and they couldn’t be cuter.

With the uniform, comes huge responsibility — and despite the silliness of their adorable looks, we applaud them and appreciate them for what they do.
