I believe every township/city/borough (whatever your local boundaries are) determine their own limits on animals. Although it is not the sole determining factor, one of the factors taken into consideration is the amount of space between properties. I live in a township that has a lot of open space, but also has a lot of condos and townhouses. I thought there was a four dog limit; however, a friend recently told me that there is no ordinance (local law) limiting the number of dogs we can have. So you need to check with your municipality.
