"When in doubt, take things slow to see how much exercise your dog is comfortable with. “On a walk, typically about 30 minutes or so should be adequate for many dogs, especially smaller ones,” says Jme Thomas, animal expert and executive director of Motley Zoo Animal Rescue. “For more interactive games like fetch or playing at the dog park, you can start with 10- or 15-minute increments of exercise and then give your dog a break.”
..."In addition, Thomas of Motley Zoo Animal Rescue points out that dogs require an outlet to be well-behaved because otherwise their energy just builds up and they don’t know how to release it, so it will manifest in bad behaviors, whether pacing, jumping, barking, or even biting. “The lack of an outlet can cause anxiety and neuroses to develop, so it is important to think of your dog like a can of soda that’s been shaken; it will explode if you’re not careful,” Thomas explains".
