Being a guide dog puppy raiser is a great thing, but it demands a lot of your time and patience. Young puppies need all your attention and future guide puppies must be in contact with you all day long. It is very important to accept, that the dog is not yours, even if he is living with you for almost a year, because you will have to give him back to the guide dog training company.
The most important part of raising a future guide dog is the socialization. As a puppy raiser, you must take your dog to public offices, restaurants, shopping malls etc. And you must use all kinds of public transportation.
