Emotional support animals, comfort animals, and therapy dogs are not service animals under Title II and Title III of the ADA. Other species of animals, whether wild or domestic, trained or untrained, are not considered service animals either. The work or tasks performed by a service animal must be directly related to the individual’s disability. It does not matter if a person has a note from a doctor that states that the person has a disability and needs to have the animal for emotional support. A doctor’s letter does not turn an animal into a service animal.
The Department of Justice (DOJ) has specifically stated in rulings that websites should be designed so they are accessible to individuals who have vision, hearing, and physical disabilities. There’s a growing body of case law where the DOJ required companies to provide an ADA compliant website and levied hefty penalties when sites failed to measure up.

^ Esshaki, Tiffany (July 21, 2015). "Remembering the 'Capitol Crawl'". C&G News. Retrieved January 15, 2016. The event, known as the "Capitol Crawl", was an image that legislators couldn't ignore, Bauer said. She had fought since the 1960s to legally protect the rights of people with disabilities, and with that heroic display, she said, lawmakers simply couldn't go back to their constituents without action.

You may have noticed that the law refers to federal agencies, so you might be thinking, “Well, this a federal issue -- how does this relate to a private business website, or how am I affected by this law?” Websites are now considered public entities since any user can access them via a computer or any other device. Think of this as a building requiring wheelchair-accessible ramps. The same basic principle applies to websites or any other technology.
“The idea of equal access, equal opportunity has sort of evolved in its application from brick and mortar to eCommerce. At first, many companies were worried about the desktop experience. Now, the concern extends to both smart phones and devices.  Wherever a consumer accesses your content – whether it be directly through the web or an app – you need to be concerned about accessibility.”
Spector v. Norwegian Cruise Line Ltd.[64] was a case that was decided by the United States Supreme Court in 2005. The defendant argued that as a vessel flying the flag of a foreign nation it was exempt from the requirements of the ADA. This argument was accepted by a federal court in Florida and, subsequently, the Fifth Circuit Court of Appeals. However, the U.S. Supreme Court reversed the ruling of the lower courts on the basis that Norwegian Cruise Lines was a business headquartered in the United States whose clients were predominantly Americans and, more importantly, operated out of port facilities throughout the United States.

The Department of Justice continues to receive many questions about how the Americans with Disabilities Act (ADA) applies to service animals. The ADA requires State and local government agencies, businesses, and non-profit organizations (covered entities) that provide goods or services to the public to make "reasonable modifications" in their policies, practices, or procedures when necessary to accommodate people with disabilities. The service animal rules fall under this general principle. Accordingly, entities that have a "no pets" policy generally must modify the policy to allow service animals into their facilities. This publication provides guidance on the ADA's service animal provisions and should be read in conjunction with the publication ADA Revised Requirements: Service Animals.

Automated testing also tends to find too many false positives, indicating something is wrong when your website does not actually need any more work. Performing manual tests on the code and pages allows testers to identify the issues that automated tests cannot detect. The solution is always a mix of manual and automated testing. Always perform both for best results, and to ensure that you meet the level of ADA compliance needed for your site. Think of it this way: automated testing is a great start, and will help you determine where there’s a need for manual testing. Both are extremely important and, if performed well, can make your site more user-friendly for all users.

Federal law isn't the only consideration for businesses. Additionally, each state interprets the law differently. Consider the case against Netflix in 2012. Lawsuits were brought in federal court in Massachusetts and California. Netflix was accused of violating the ADA by not offering "closed captioning" options for its Internet streamed movies. Illustrating the complexity of this issue, the courts reached completely opposite decisions. Massachusetts held that Netflix must comply with the ADA, while the California court found that Netflix did not fall under the ADA's definition of "public accommodation."

The Americans with Disabilities Act (ADA) prohibits discrimination against people with disabilities in several areas, including employment, transportation, public accommodations, communications and access to state and local government’ programs and services. As it relates to employment, Title I of the ADA protects the rights of both employees and job seekers. The ADA also establishes requirements for telecommunications relay services. Title IV, which is regulated by the Federal Communications Commission (FCC), also requires closed captioning of federally funded public service announcements.
Title III of the ADA requires that every owner, lessor, or operator of a “place of public accommodation” provide equal access to users who meet ADA standards for disability. With roughly 1.66 billion people around the world making online purchases in 2017, one might reasonably presume that this concept extends to websites, but from a legal standpoint, there is a surprising amount of grey area.
Case law has been the most helpful in illuminating the implications of the ADA for websites.There have been lawsuits involving companies like Expedia, Hotels.com, Southwest Airlines, and Target as defendants and primarily featuring accessibility organizations as plaintiffs. These cases had mixed results, but each helped clarify the ADA's jurisdiction on the web. 
Title III also has applications to existing facilities. One of the definitions of "discrimination" under Title III of the ADA is a "failure to remove" architectural barriers in existing facilities. See 42 U.S.C. § 12182(b)(2)(A)(iv). This means that even facilities that have not been modified or altered in any way after the ADA was passed still have obligations. The standard is whether "removing barriers" (typically defined as bringing a condition into compliance with the ADAAG) is "readily achievable", defined as "...easily accomplished without much difficulty or expense".
Many people may not know that ADA compliance extends to websites now. Your website, of course, isn't discriminating based on not having an elevator or ramp, but it may not be using appropriate colors, fonts and file types. Hard-to-see colors and fonts can discriminate against people with visual impairments, as can certain file types that don't allow computers to read text out loud for those who need such an accommodation. Read on to learn more about how the ADA may affect your business and how you can test your website for compliance.

• Understandable: Make sure it's easy for all users to comprehend the information on your website. Recommendations include making the text readable — which includes using a mechanism to help identify definitions of words or phrases used in unusual ways — expanding abbreviations and including language that's at the lower secondary education level, if possible, or making available a version that doesn't require advanced reading ability. The WCAG 2.1 offers additional insight on how to make your website understandable.

The idea of federal legislation enhancing and extending civil rights legislation to millions of Americans with disabilities gained bipartisan support in late 1988 and early 1989. In early 1989 both Congress and the newly-inaugurated Bush White House worked separately, then jointly, to write legislation capable of expanding civil rights without imposing undue harm or costs on those already in compliance with existing rules and laws.[27]
In some circumstances, longer and more detailed text will be necessary to convey the same meaningful information that other visitors to the website can see. For example, a map showing the locations of neighborhood branches of a city library needs a tag with much more information in text format. In that instance, where the map conveys the locations of several facilities, add a “longdesc” tag that includes a text equivalent description of each location shown on the map – e.g., “City Center Library, 433 N. Main Street, located on North Main Street between 4th Avenue and 5th Avenue.”

In the employment setting, employers may be obligated to permit employees to bring their “service animal in training” into the workplace as a reasonable accommodation, especially if the animal is being trained to assist the employee with work-related tasks. The untrained animal may be excluded, however, if it becomes a workplace disruption or causes an undue hardship in the workplace.
Your site would need to have a text only option, with all functionality accessible through a keyboard for visitors with mobility issues. Once you make these and other changes to meet ADA guidelines, your site would need to be tested by a website development company familiar with ADA compliance issues to be sure that visitors who use assistive technology such as screen readers are able to access your web content fully.
Now you know that some types of content and format on webpages can pose barriers for people with disabilities. The next steps are to develop an action plan to fix web content that is currently inaccessible and implement procedures to ensure that all new and modified web content is accessible. The website accessibility checklist included in this section helps you assess what needs to be done.

An example is Patagonia Works, Inc. which had a complaint for a permanent injunction filed against it in the United States District Court stating, Under Section 302(b)(1) of Title III of the ADA, it is unlawful discrimination to deny individuals with disabilities an opportunity to participate in or benefit from the goods, services, facilities, privileges, advantages or accommodations, which is equal to the opportunities afforded to other individuals. 42 U.S.C. 12182 (b)(1)(A)(ii). Below is a summary of what the lawyers asked the court for.

A. If the patient is not able to care for the service animal, the patient can make arrangements for a family member or friend to come to the hospital to provide these services, as it is always preferable that the service animal and its handler not be separated, or to keep the dog during the hospitalization. If the patient is unable to care for the dog and is unable to arrange for someone else to care for the dog, the hospital may place the dog in a boarding facility until the patient is released, or make other appropriate arrangements. However, the hospital must give the patient the opportunity to make arrangements for the dog's care before taking such steps.

Part of Title I was found unconstitutional by the United States Supreme Court as it pertains to states in the case of Board of Trustees of the University of Alabama v. Garrett as violating the sovereign immunity rights of the several states as specified by the Eleventh Amendment to the United States Constitution. The Court determined that state employees cannot sue their employer for violating ADA rules. State employees can, however, file complaints at the Department of Justice or the Equal Employment Opportunity Commission, who can sue on their behalf.[19]
