The study referenced looked at thousands of dogs, asking their owners questions about impulsivity, hyperactivity, and inattention, the three main traits we usually associate with human ADHD.
I feel that dogs have the right to go out every day and run until they're tired. Go home, eat, and sleep. If a dog was impulsive, etc., after that then ADHD might be the answer. But so many dogs, especially after Covid when shut-in humans adopted/bought dogs in a frenzy, don't get to live a dog's day of activity including chasing squirrels playing with other dogs, and just doing a dog day, but spend most of their time indoors after a quick walk around the block, they might well be accused of being hyperactive. I've always had terriers, grew up with them, and as big thinkers they need to be kept occupied. Humans just need to make the time to let them live dog lives.
