你不需要办许可.你应该带他去兽医那打各种防疫针(包括rabbie)还要买heartworm 的药.我建议你还要给他上防跳蚤的药.否则他会把跳蚤带回家

You need train him to be housebroken.Just take him out as often as possible .Then he will know how to use the bathroom outside.If you dog is still a puppy,You can buy a crate,then put him in the crate when you are not around.Dogs will now mess their crates.So your dog can learn when he should relieve himself ,when he should not.Raising a puppy needs a lot of a lot of work.But if you really like dogs,the happiness and accompanion your dog brings to you is pricelese.You can train him and play with him.That's a lot of fun.

I have two dogs and I feel so lucky I can be with them everyday.I just can't imagine my life without them.Good luck
