Ideally, the dogs will work for ten or more years, after which they are retired. After retirement the dog may continue to live with the client or go to live with a family member or friend. "Successor" dogs are provided free of charge and as soon as possible after the retiring of the previous dog. Some dogs might lack the right temperament, physical health, or stress-resistance for being an assistance dog. At any point in training, from puppies to placement with a client, a dog may be "washed-out" and/or career-changed. If a dog is unable to complete PAWS' training, but still has the right temperament for assistance dog work, it may be transferred to PAWS' guide dog partner, Leader Dogs for the Blind for training there. Other "working careers" are also options for former Paws Dogs, including working for US Customs, Police Departments, or Arson Detection.
