1People who make no time to train their puppies in the proper ways
We do understand that dog training is quite defying, but it is not an impossible thing to not do. Many owners don’t pay heed to how to train a dog with given methods and ways which differ given the concerned dog breeds.
There are some of the easiest dogs to train, but if attention is not paid during the process, dog obedience training will become a real issue.
If you are too busy to own a dog, and you have no clue about the best exercise for dogs to be trained, then don’t own any dogs at all. If you can afford a trainer, you can hire service dog training, but come on! Your dog needs to bond with you, not with some stranger.
2People who don’t devote some of their time to read about dogs
There is a reason why dog books are sold and dog articles are published. The reason is certainly not storing them on the shelves of libraries.
If you are a dog owner or interested in owning one, you need to read such writings to enlighten yourself about the life and needs of your future buddy.
Your dog will need care, shelter and more importantly a healthy puppy diet (dog foods from brands like Taste of The Wild Grain or Purina Beyond Grain and the like).
This is not enough, if you cannot run an in-depth study about the surrounding environment where your dog will live, the most common bacteria and diseases to affect him and similar pieces of information, owning a dog might not be your thing.
