Inherited tenant violating pet policy

[Ross Bernard]

I purchased a house with an existing 3 yr tenant. The lease states no pets allowed but it sounds like the owner allowed her two pit bulls. My insurance policy won't cover vicious breeds. The tenant keeps up the place well considering she has 6 kids. Section 8 pays 100% rent.

I've met the dogs and they weren't aggressive toward me coming in their house. Would you ignore the dog situation or demand they be removed?
