Every pet parent has experienced it: You’re having a perfectly lovely time, then suddenly your dog just … stops. One day, she was out walking with her own pup, Mena, when Mena suddenly stopped just as they entered the park. “Learning dog body language and knowing your dog is super important, as these two things could help you better understand the reason behind your dog becoming stuck,” she says. “It is important to understand the ‘why’ behind the lack of movement,” Dr. Kuntz says. Figure out what motivates your dog, advises Dr. Kuntz, noting that it could be food, pets, or praise.
