If it was the country and not city I might say your trusty 22 rifle would to the trick but I dont want PETA involved..lol Pest control is expensive here and even if you had sturdy cans they are pretty good at getting into trash.

It is thin but sturdy.

ESA's must always be on a leash and under control in public areas.

A lot depends on how much leash you're comfortable handing over.  

In addition to a renters insurance policy and vaccination records from their vet, we limit the size of the dog. we also add to our property rules that the dog must always be on a leash, they pick-up the dog poop and the dog must not disturb the other residents if this is a multi-family complex. 

In my area leashes are not optional and all dogs must remain in full control of the owner at all times. 

(I want it to be tenant-sturdy). 

Letting your dog run around your front yard off a leash is illegal.

If a person/tenant wants to leave a lease nor a leash will hold them.
