Are Autism Assistance Dogs suitable for children of all ages?
When should an Autism Assistance Dog be introduced to a child with autism?
Answer:
These questions, coupled with an increase in interest by families in acquiring a dog for their child and Autism researchers attempting to assess the effectiveness of dogs in support of a child and family. However, it is not yet possible to conclusively state that assistance dogs (also called service dogs) are effective companion for an Autistic child, let alone make recommendations as to the desired characteristics and training of dogs or suitable child and family characteristics (e.g., child age, level of functioning, behavioural issues; family type and dynamics). This is because the studies published to date have many limitations.
- Many studies rely on parental reports of child behaviour and functioning and family wellbeing rather than direct observation or objective assessment with reliable scales. This increases the possibility that reported changes to child behaviour and functioning and family wellbeing after the introduction of an assistance dog are perceived rather than real (the Placebo Effect). The expectation, belief or hope that an intervention will be beneficial can lead to a perception that it is effective when in reality it may not be. Therefore, it is always best to back up parents’ judgements with objective measures of changes, such as structured observation and/or assessments of the child and/or family. Many funding organisations ask for this kind of evaluation before they commit themselves to funding an intervention, such as assistance dogs.
- Many of the studies include only a small number of children or families, and given the variability of Autistic children, they often find inconclusive results which can’t be interpreted easily. This is not helped by the large age range of the children included in the studies (for example, 8-18 years; 3-15 years, 4.5-14 years and so on) and by the fact that all studies only include high-functioning Autistic children. Therefore, we cannot say for which children/family a dog would be helpful and for which it would be ineffective or, worse, too risky. We also don’t know at what child-age a dog should be introduced to a family, or indeed, whether a young dog is better than an older one.
- Few studies have included a control group (child/family without a dog) or control condition (same child/family before introduction of a dog). Also the length of time a dog has been in the family is usually not reported. This makes it difficult to know whether any changes in the child’s behaviour and function and family’s wellbeing is because of the dog or something else, including the child’s natural developmental progression.
- Some studies do not discriminate between trained assistance dogs and pet dogs and to our knowledge nobody has investigated whether one is more effective than the other. We also don’t have any evidence for what abilities an assistance dog should be trained for to best be able to support Autistic children and their families. Considering that a trained dog may not be easily obtainable and expensive, this is a research project that is desperately needed.
Preliminary findings to date

Attachment to dog
It seems that Autistic children can get attached to dogs and that the presence of a dog can lead to reduced stress and anxiety levels in the child. Their tendency to ‘escape’ from home may also be reduced, because the dog may be trained to watch out for escape attempts and prevent them. Further, if the dog is allowed to sleep in the same room as the child and if the child can tolerate it, it may lead to better sleep for the child (and consequently the family). All these benefits are of great help to the child’s family and contribute to their wellbeing.
However, not all Autistic children get attached to dogs; some remain fearful or worse, if they have aggressive tendencies, may hurt the dog, which of course may lead to the dog defending itself by hurting the child. Some children also have sensory issues with a dog (being sensitive to the fur, the noises a dog makes, its smell etc). Therefore the child and dog need to be supervised closely, especially in the beginning. There is some evidence that a small dog may be better than a large dog, and a dog with a calm and patient temperament is better that a boisterous dog. In one study it was found that a dog may be an additional burden to a family already experiencing increased stress due to having to care for an Autistic child.
Changes in behavior

Some studies report that social interactions, play behaviour and communication improves when the child has developed a good relationship with a dog. However, these findings remain to be corroborated by independent observations or assessments. Only one study (Carlisle, 2014) to date has compared two groups of Autistic children, one that had dogs and the other without. There were very few differences in the level of social skills and number of problem behaviours in the two groups. But there was some evidence that the longer the dog was in the family, the better the child’s social skills and behaviour.
Encouraging indications that the presence of other animals (guinea pigs) can increase positive social behaviours in Autistic children come from another recent study by O’Haire, McKenzie, Beck and Slaughter (2013). They observed Autistic children during play sessions in school either with toys or with guinea pigs. Their social behaviour with their peers during these sessions was scored by independent observers on standardised scales. Autistic participants were found to show more talking, looking at faces, and making tactile contacts and received more social approaches from their peers in the presence of animals, compared to toys. They also displayed more smiling and laughing, as well as less frowning, crying, and whining in the presence of animals.
Conclusion
The results of our recent studies are encouraging and we await further well-designed studies. Given of the scarcity of reliable evidence to date we are unable to make recommendations either for or against dog ownership in families with an Autistic child.

We have a beautiful Lab that we bought from a breeder. She had been around a child with autism and she was ver laid back.
She isn’t trained as an assistant dog but she will comfort my son when he has a meltdown, she also calms his anxiety.
My 9rd old son has had a cat since he was 6. They has a connection that is amazing. If he is having a meltdown she appears from nowhere and starts rubbing around his legs. They do this affectionate head butting ritual and she is only like it with him, nobody else. They adore each other and she is very calming for him.
