Task 1. Read the text and choose the correct answers to the questions. Dog Tricks It's fun to have your dog do tricks when your friends come to your house to hang out. Seeing Rover play dead, talk, or open the refrigerator is quite a crowd pleaser. But tricks are not only great entertainment. They are also a great way to bond with your dog, integrate your dog with your family, and keep your dog physically and mentally challenged. Experts say that teaching your dog tricks is not all that difficult, but patience is crucial. If you don't have patience, you will never be able to teach your dog tricks. There are three steps to follow in order to successfully teach your dog a new trick.
