Questions about whether dogs can have autism are appearing more frequently, particularly as awareness of behaviour and neurodiversity grows.
Recent research has explored whether some dogs show patterns in behaviour and brain function that resemble those studied in human autism. Some media reports have described this as dogs being “neurodivergent”, but researchers themselves use more cautious language such as “autism-like traits”.
Current evidence does not support a clinical diagnosis of autism in dogs. Instead, the research focuses on understanding differences in how some dogs process social interaction, learning and their environment.
Key Points
- Dogs cannot be diagnosed with autism
- Some dogs show behaviours that look similar to autism traits
- Recent research has explored genetic links, including the Shank3 gene
- Differences have been observed in social behaviour and brain responses
- Scientists describe these as “autism-like traits”, not a condition
What the Study Looked At
Recent studies have focused on how dogs respond to social interaction, including eye contact, attention to humans and how they process information.
One 2025 study examined dogs with a variation in a gene called Shank3, which is also linked to autism in humans.
Other research has explored behaviour in family dogs, looking at social engagement, learning patterns and how dogs respond to new or changing situations.
Some studies have also examined brain activity during interaction between dogs and humans.
What Researchers Found
Across these studies, researchers observed that some dogs:
- paid less attention to human faces
- made less eye contact
- showed differences in how they responded to social interaction
In wider pet dog populations, some dogs were also found to:
- engage less socially
- respond differently to new or changing situations
- show variations in how they process sensory information
Studies looking at brain activity also identified differences in how some dogs process social interaction at a neurological level.
What This Means for Dog Guardians
- Some dogs may naturally interact with the world in different ways
- Lower social engagement or unusual behaviour does not mean something is “wrong”
- Behaviour can be influenced by genetics, learning history and environment
- The focus should be on understanding and supporting the individual dog
Why Brain Function Is Being Studied
Earlier research focused mainly on behaviour.
More recent studies are examining what happens in the brain during social interaction. This helps researchers understand whether behavioural differences are linked to how dogs process information, rather than relying only on observation.
Where the Science Stands
Current research shows that some dogs display behaviours and biological traits that overlap with those studied in human autism.
However, there is no recognised clinical diagnosis of autism in dogs.
Scientists use terms such as “autism-like traits” or “ASD-like behaviour” to describe patterns they are observing, rather than defining a medical condition.

FAQ’s
Can dogs be diagnosed with autism?
No. There is currently no recognised clinical diagnosis of autism in dogs.
Why do some dogs seem autistic?
Some dogs may show behaviours such as reduced social interaction or sensitivity to their environment. Research suggests these differences may be linked to genetics, learning history, or individual temperament.
What is meant by “autism-like traits” in dogs?
This term is used by researchers to describe behaviours that resemble patterns studied in human autism, such as reduced eye contact or differences in social engagement.
Is there a genetic link to autism-like behaviour in dogs?
Some studies have explored genes such as Shank3, which is linked to social behaviour in both dogs and humans.
Should I be concerned if my dog behaves differently?
Not necessarily. Differences in behaviour are common. If you are concerned, seeking guidance from a qualified professional can help you better understand and support your dog.
