each breed is unique and bring certain challenges. retrievers and shepards tend to be more energetic and need more stimulation, both physical and mental. make sure you have room to run and time to spend with these animals. - a dog is only as good as its owner. never train your dog to be aggressive, a dog will naturally protect his pack, and you will be his pack. no aggressive training is needed for this. - don't physically discipline your dog, if you do not know how to train without being physical, take a training course with your dog. - understand that this is an animal (even though we love them as part of our family) and will respond to threatening behavior as an animal with teeth and claws. - before getting a dog, make sure you are able to handle the costs of owning a dog.
The kind that person (or family) is prepared to take care of. Ask yourself questions like, "what level of activity are you prepared to live with," "how much time each day are you able to dedicate to caring for this dog." "Can you afford vet care for regular preventative care as well as emergency care?"
Visit your local animal shelter. There you can I interact with different dogs. you may find your best friend there!!! rescued dogs are the best breed!!! I agree with the other posts though, make sure you are ready for an animal.
