My aunt dealt with the exact same problem with a family that rented the house adjacent to theirs.

The law is virtually identical up there. So, my aunt mailed a letter clearly advising the new tenant of the situation via certified return receipt, cc'ing the county Animal Control Dept. in the process.

From that point on, when the dogs became a nuisance, they called Animal Control and the dogs were removed from the property.

The owners had to pay a fine to retrieve their dogs from the County. By the third offense, they finally made good on the promise to send the dogs to obedience school. The problem was resolved completely in less than 2 months.
