Like with humans, the symptoms and severity of autism in dogs can vary widely from case to case. Some common signs of high-functioning autism in dogs include social withdrawal, unresponsiveness to people and surroundings, and hyperactivity or destructive behaviors.
Difficulty communicating, including avoiding eye contact and expressing themselves differently than other dogs. Repetitive/compulsive behaviours, like circling, tail chasing, or obsessive chewing. Hypersensitivity to stimuli, like petting or sudden noises. Anxiety or aggression, often associated with specific triggers.
Repetitive motions are also a characteristic of autistic behavior, and can include a wide variety of actions such as circling a room over and over again, or chronic tail-chasing or obsessive teeth grinding. Other repetitive behaviors include lining up toys or other objects, or obsessive chewing.
Can a Dog Have Autism? While some of these behaviors are unique to humans, researchers have found that, in fact, ASD can occur in dogs, but it's called canine dysfunctional behavior (CDB). Researchers believe that canine dysfunctional behavior is an idiopathic condition, meaning that the cause is unknown.
But can dogs have ADHD? The answer is more complex than you may think. While hyperactivity in dogs can be common, other ADHD-like behaviors may stem from a rare condition known as Hyperkinesis.
Dogs and young children have a lot in common. They're excitable, exploratory, and can suffer from symptoms of ADHD—although hyperactivity in dogs is technically known as hyperkinesis.
That said, some animals do display autistic-like traits, such as a tendency toward repetitive behaviour or atypical social habits. Bull terriers, for example, are especially prone to repetitive tail chasing, which some experts liken to the spinning that is sometimes seen in children with autism.
It is unlikely that dogs have Down Syndrome as some humans do. However, they can suffer from different conditions that are like Down Syndrome. Dogs can experience heart defects, stunted growth, difficulty learning, and loss of vision or hearing.
Exercise and physical activities are especially important for individuals with symptoms of autism; they can help to improve motor skills, reduce anxiety, and can even lead to improved social functioning, and this is true for both humans and canines.
Outside of medical and institutional settings, therapy dogs have become popular in the autism community for their calming influence and ability to promote social interaction. Many but not all therapy dogs have special training.
Canine cognitive dysfunction (CCD) is a behavioral syndrome that affects old dogs. Dogs with CCD show behavioral alterations such as disorientation, altered interactions with owners, other pets and the environment, sleep-wake cycle disturbance, house-soiling and changes in activity [14].
Dogs, just like people, can experience developmental delays. Those delays can be genetic in origin, or they can be due to something that happened during the dam's pregnancy, during birth, etc. Some puppies get stepped on or laid on, and some are born as singletons or the runt of their litter.
More recent research has used the house mouse (Mus musculus) to model autism because it is a social species.
Spontaneously hypertensive rats (SHR) were found to be the best characterized and also currently the most appropriate model of ADHD [45].
The History of Bipolar Disorder
To date, no such disorder has been identified for dogs despite the fact that dogs can sometimes display what appear to be sudden mood changes. However, as veterinary experts have observed this is usually a reaction rather than a biochemical imbalance that can lead to these extremes.
Dogs with ADHD demonstrate exceptionally short attention spans and a high degree of impulsiveness that makes it impossible for them to focus on one task for long. They are easily distracted. In contrast, most of the high-energy dogs that clients bring to me will focus very quickly on the click-and-treat game.
HELSINKI, Finland (StudyFinds)— Attention-deficit/hyperactivity disorder (ADHD) is not something that just affects people — it may be a problem among our pets too.
The true test of ADHD is to give your dog a prescribed stimulant under controlled clinical conditions and then monitor changes in heart rate, respiratory rate, and behavior. For a dog with ADHD, a stimulant will reduce the symptoms.
Studies show that 12–15% of dogs exhibit hyperactivity and impulsivity, and 20% exhibit inattention — and that those qualities are highly heritable but also influenced by environmental factors, just like they are in humans.
A trait similar to SPS has recently been identified in dogs (“canine Sensory Processing Sensitivity”, cSPS). In children, this trait interacts with parenting factors to influence emotional and mental development, which in turn are linked to behaviour problems.
The most common “developed abnormal behaviors” are aggression, fear reactions, inappropriate elimination, vocalization, altered facial expression, altered posture, restlessness, and hiding [4]. Pain has also been related to repetitive behaviors [5].
The result is the famed fight-or-flight response. In reality, there are four responses you might see in pets, says Landsberg-fight, flight, fidget or freeze.
