First tenant call this weekend

[Maurice Caulk]

Hello everyone! I wanted to share with you my first "service call" with my first rental.

So my Tenant called me this weekend saying theres a problem. She ccontinued to say her next door neighbor dog continues to come over and takes a poop in her backyard! She says she went over there and try to talk to the neighbor  At first she refused to answer the door but once she finally opened it she said  "If you want me to keep my dog  out of your yard tell your landlord to fix the fence and then I'll try to keep my dog out of your yard"

What the neighbor is referring to, its a divider fence  in between the two houses (town homes) the Landscaping slopes so there's a small Gap underneath one side of the fence. I already went over there to fix it even though I didn't have to do anything. 

So I was wondering what would you have done? Also what would of been the proper way tof handle the situation?
