Here is the fox terrier rescue contact page. http://www.foxterrierrescue.net/listing.html

Although, if you are not the legal owner of the dogs, there is little a rescue can do to help you.

You could contact the owners, and see if they will give you the dogs, then you could turn them over to a rescue.

Or, you could contact your local animal contol or humane society and have them pick up the dogs. Then tell fox terrier rescue where they dogs have gone, and they can get them from the shelter.

Good luck!
