Tenant issue with neighbor's dog

[Gina McKee]

My tenant just informed me that the next door neighbor's dog is ripping pieces off the fence dividing the two properties and eating them, thereby creating holes in the fence through which it is using to enter the yard of my tenant. It is then defecating in the yard. The dog is generally a nuisance to my tenant, and it appears (according to my tenant) to be heavily neglected. I advised my tenant to contact animal control for the city to come and assess the situation. Does anyone have any advise about how I should deal with this situation?

Thanks!
