Neighbor dog issue- keeps breaking the fences- landlord

[Mak K.]

So I have a property rental where the neighbors dog keeps breaking the fences. It is an aggressive dog. The dog breaks the fence and we get a letter from HOA.

how should we handle this situation? As a landlord should I write a letter to the neighbor or HOA or call animal control!? Or should the tenant do it?

the tenant is a single mom working to meet the ends meet and nice lady. So trying to help the situation as landlord but I do not want to overstep and take this issue on my hands if there are any risk?
