My fat man will definitely like it. Our big fat golden retriever feels tired after two steps, and his tongue is tilted to one side ~ ~ ~ This exercise is very beneficial. When he comes out, there will definitely be tight lines in his chest and abdomen, unlike our golden retriever, which is a rectangular body. Now when you run, you should use chains to restrain you. Don't use the strap, use le neck's. If he runs too fast or runs around, it can play a certain inhibitory role. We can't let him make trouble innocently. The main thing is to control its speed. If it jogs, let its hooves run separately. Don't jump into two groups (of course, if he jumps into two groups to keep up with you, that's another matter). After a long time, the speed of you two will be unified. Remember, if you are dissatisfied with something, let it change, and you can't wait until you can't stand it.
