Scientists now say dogs can be autistic like humans: Here are the signs to look for in your pets

Some experts believe dogs can show autism-like traits, though there is no official diagnosis. Veterinarians often call it “canine dysfunctional behavior.”

Key signs fall into three areas. Repetitive behaviors like tail chasing, pacing, or constant paw licking. Social changes such as avoiding eye contact, withdrawing, or losing interest in play. And sensory sensitivity, including strong reactions to common sounds or touch.

If these behaviors are frequent and disrupt daily life, experts recommend a veterinary evaluation to rule out other medical issues. Consistent routines, calm spaces, and positive training can help reduce stress and support your dog’s well-being.
