Removal of Tenant's aggressive animal

[Derrick C.]

My Oklahoma tenant has a pitbull that has been going on the neighbor's property. The neighbors said they are scared of the dog b/c it is aggresive and wont back down when they tell it to go away. The concern is that it will attack one of the children or animals on their land. Their lease states the tenant agrees to remove any animal who displays violent behavior. My questions are: how do I go about telling them to remove their animal from the premises and do I need to give a specific timeframe? How do I verify that this has been done? With the new laws in place because of the pandemic, can I do this? Thanks in advance!
