However you must be selective in choosing dogs, you must not allow any dangerous breeds.

Some people, on the other hand, have studied dogs for many years and have wonderful "agressive" breed dogs.

You can discriminate however you choose against breeds, sizes, etc.

-require that any renter that owns a dog (of any breed) provides documentation that they have been to some form of obediance class.

I have always been a animal person but I have had to implement a no dog policy cause my insurance won't allow so many different breeds so have found just easier to not allow them.  

Just another note,  if you do accept dogs, we require a minimum of $100K in renters insurance.... also, check with your insurance company to verify which breeds are accepted. 

All prospects, after you PRE-SCREEN them over the phone for (1) credit score, (2) income, and (3) dogs (no aggressive breeds; violate your insurance) must go to one of those showings. 

2) Verifying the breed of the dog: I understand in talking with insurance companies that the tenants provide the type of breed during the renters insurance app process.

The mixed breed dog has some sort of oil on his coat.

I typically do $125 non-refundable or $200-250 refundable - but determine what fits best in your market and go with it.Mandating a separate insurance policy is probably overkill unless they have a breed that is specifically excluded by your own policy.
