Bringing a Service Dog or Support Animal to Work in Colorado

Workplaces follow different rules than stores. Colorado's anti-discrimination law reaches every employer, and requests run through a back-and-forth process. Here is how to ask, what your employer may ask you, and what happens if the answer is no.

Why Work Rules Differ From Public Places

A shopper with a service dog walks in with no paperwork. An employee's request is handled as a workplace accommodation, which works differently.

Stores

Two questions only

Businesses may not ask for documentation about a service dog.

Workplaces

Documentation can be requested

When a disability or need isn't obvious, employers may ask for reasonable information.

Both

Behavior matters

A disruptive or uncontrolled animal can be addressed in either setting.

Which Law Covers Your Employer

This is where Colorado reaches further than federal law.

15+employees

Federal ADA, Title I

Applies to private employers with 15 or more employees, plus state and local governments.

1+employee

Colorado Anti-Discrimination Act

Covers Colorado employers regardless of size. C.R.S. 24-34-803 separately addresses service animals in employment and bars extra charges for them.

How to Make the Request

No magic words are needed, but a clear written request makes the process smoother.

Tell your manager or HR in writing

Say you have a disability and are asking to bring your animal as an accommodation.

Describe what the animal does

For a service dog, the trained task. For a support animal, how it helps with your condition at work.

Answer reasonable questions

Provide documentation from a provider if your employer asks and the need is not obvious.

Talk through the practical details

Where the dog rests, relief breaks, and any coworker concerns.

Get the outcome in writing

Whether approved, modified or denied, ask for a written answer.

What Your Employer May and May Not Do

May

Ask for documentation of a disability that isn't obvious

Require the animal to be under control and housebroken

Suggest an alternative that meets your need

Decline when there is a real undue hardship

May not

Charge a fee for a service animal

Share your medical details with coworkers

Ignore the request or refuse to discuss it

Punish you for asking or complaining

When a Coworker Has Allergies or Fears Dogs

Both employees' needs count. Employers usually look for arrangements like these before saying no.

Separate workspaces

Seat the two employees apart.

Air filtration

HEPA filters and more cleaning.

Schedules

Different shifts or meeting setups.

Remote days

Where the job allows it.

Emotional Support Animals at Work

Colorado's 2026 emotional support animal law is about housing. At work, a support animal is simply one possible accommodation, weighed like any other.

  • The employer considers your disability-related need
  • Other accommodations may be offered instead, if they work
  • Documentation from your provider is often part of it
  • A letter written for housing may not address your job

Where Undue Hardship May Come Up

An employer must show real difficulty or expense, judged case by case. These settings raise the question more often.

Sterile or clinical areas

Operating rooms, labs and clean rooms may limit animals in certain spaces.

Food production

Kitchens and processing lines have strict hygiene rules.

Hazardous sites

Heavy equipment or chemicals can put an animal at risk.

Your Side of the Deal

Keep control

Leash, harness or voice control at all times.

Handle cleanup

Relief breaks and any mess are your job.

Pay for damage

Colorado law makes the handler liable for damage the animal causes.

Stay current

Vaccinations and local licensing up to date.

300days

If Your Request Is Denied

Employment discrimination complaints generally go to the Colorado Civil Rights Division or the EEOC within 300 days of the discriminatory act. The two agencies share charges.

Retaliation for asking is a separate violation. An employment attorney can help you choose the right path.

Workplace Animal Questions From Coloradans

Can I bring my service dog to work in Colorado?

Usually, yes. Colorado law protects employees who use a trained service animal, and the Colorado Anti-Discrimination Act applies to employers of every size. An employer can decline only in limited cases, such as when allowing the animal would be an undue hardship.

Can I bring an emotional support animal to work?

You can ask. An emotional support animal at work is treated as an ordinary reasonable accommodation request, so the employer looks at your disability-related need and the workplace before deciding. It is not automatic.

Can my employer ask for documentation about my service dog?

Often, yes. Unlike a store, an employer handling an accommodation request may ask for reasonable documentation of the disability and how the animal helps, when those are not obvious. The employer should keep that information confidential.

Does a small business in Colorado have to allow a service dog?

The federal ADA's employment rules apply to employers with 15 or more employees, but the Colorado Anti-Discrimination Act covers employers of any size. Small Colorado employers therefore still need to consider the request.

What if a coworker is allergic to or afraid of dogs?

Employers are expected to look for a solution that works for both people, such as separate work areas, air filtration or schedule changes. A coworker's allergy or fear does not automatically defeat the request.

How long do I have to file a workplace discrimination complaint in Colorado?

Employment complaints generally must be filed with the Colorado Civil Rights Division or the EEOC within 300 days of the discriminatory act. Filing with one agency is usually shared with the other.
