When many people in the U.S. were forced to work from home in the early days of the coronavirus health crisis, they decided to get a dog. People say having a dog offers companionship and a reason to get exercise. After all, dogs need to get outside and walk. Adriana Magarin is a new dog owner in Houston, Texas. She said she got a dog because, “you can only read so many books, you can only listen to so many podcasts.” In most cases, dog owners take their animals for walks with a leash. But in some places, there are open spaces where dogs are permitted to play with other dogs without wearing a leash. These places are called dog parks. Expert dog trainers say social activities that can happen at dog parks are important for the animals, especially young ones, known as puppies.
