How do you know? Are you privy to their medical records? If so you’re bound by confidentiality requirements not to discuss them in a public forum.
Or is your (mis) ‘diagnosis’ based on your (incorrect) belief that disabled people present in a specific way and are easily identified?
Be very careful assuming what you think you know. If your rationale for refusing an assistance animal is based on your misdiagnosis then you may be personally liable for any compensation claim for discrimination.
