Stray dogs are generally fragile and afraid of people because they have been abandoned. I think you should let him adapt to the new environment and you first, be kind to him and never abandon him again. He will be very obedient when he gets used to you, because you have given him a home, which is very important to people and animals. The problem of defecation can be solved when walking the dog. It is best to do it once in the morning and once in the evening. There is no time.

Keeping a dog can't just be fun for a while, it's a commitment to his life. I hope you can take care of this abandoned dog once ~

Look, you said you were still a student. I hope I can't take him when I graduate and find him a good family to adopt. It would be pitiful to wander again. ........
