A good breeder will probably ask you questions about your lifestyle, size of your family, where the puppy will live, whether you have a fenced yard, your training beliefs, etc. Reputable breeders should be willing to provide you with references. Find out what the breeder requires of you as the purchaser and make sure that you are comfortable with these requirements. Find out what grooming is involved in owning the dog you have chosen. Find out how much exercise the breed of dog you are looking for requires and be prepared to supply this exercise on a regular basis.
Springers are a very high energy dog.
Springers should be walked on a regular basis. A puppy should be walked on a buckle or snap collar, not a choke. Puppies' bones are not yet formed and can be injured easily. A fenced yard or an adequate exercise area is a necessity. Most breeders recommend formal obedience.
