Waffle的小模样儿真聪明。MM提了个很好的问题，首先听医生的，其次，小狗锻炼要掌握度

这里有两篇文章，推荐2个月之内的小puppy的运动量

Puppies need five minutes of exercise per month of age up to twice a day, according to the U.K. Kennel Club. In other words, a 3-month-old puppy will need 15 minutes of exercise while a 4-month-old will need 20 minutes. This may take the form of low-impact activities like swimming or playing with small dog exercise balls. You can also take your puppy out for short walks on a leash. However, if he starts to sit down, give him time to rest. If he does not start walking again, you may have to carry him home.

至于做什么运动要看你与他斗智斗勇了，哈哈，一般丢球是个很好的运动，其次，给他一些智力游戏，有一种球是中空的，可以塞些treats，他一边咬，treats就一边掉，可以让他kills很多时间。另外，放一大浴缸水让他玩儿也是个办法。下边是5个比较简单的puppy games

需要提醒的是，在《教你如何读懂犬言犬语》这本书里，矢岛信一指出，养狗要保持非常淡定沉稳的环境，即使狗狗很激动浑身充满能量，主人也不能随着他去疯，总之不要给他造成可以乱疯乱跑的环境。但是我自己也很难做到这点，看到狗狗高兴的疯跑，快乐地奔过来迎接，自己也会跟着兴奋起来。可实际上主人这种hyper的状况很不利于训练狗。
