Tenant's Dog Bites Roofing Contractor...Now what???

[Dave S.]

The headline says it all... The roofer ended up with 5 punctures which drew blood. The contractor is being reasonable and has requested the tenant to have a blood test performed on the dog to look for rabies. The bite happened about 2 weeks ago and I dont believe the blood work was done yet. The property manager sent a letter to the tenant instructing him to remove the dog from the premises...My tenant then, out of the blue, hired an attorney....Basically saying that we didnt give him "a 2nd chance" with the dog. The lease clearly states that if an animal attacks a human being without provocation that I have a right to have the animal removed. The letter from the his attorney did state that he wants to settle this amiably and stay in the property till the end of the lease. 

Thoughts on the matter? If i dont do anything about this now, Im concerned about it happening again (what if it was a young child)? Nevertheless, If i allowed the dog to stay wouldnt I be liable if something would happen again?

Next steps?

Property manager wants to file for breach of lease based on harboring a dangerous dog and now this is starting to cost me money.
