If you choose an electronic dog, pay attention to whether it is a two-in-one fixed mobile electronic dog. Many friends who don't know about this may buy a single mobile or single fixed electronic dog. In theory, it is cheap, but in fact, the money is wasted.
as for what kind of electronic dog to buy, this is not recommended, because some electronic dogs are used for regional data, which may be very useful in a certain area, but not necessarily in other places. Therefore, this thing should also refer to your actual use area. Of course, there are also electronic dogs that do well in national data, depending on how you choose.
