Many people do not want to adopt a dog from the shelter because they fear that the dog automatically learned bad behaviors and that it will be easier with a puppy. I am here to say that this is simply not true and that a puppy actually requires more work. Unless you want the dog for something else besides just a pet then I might say get a puppy to quickly prevent bad behaviors. I still might suggest adopting a dog even then. Although it is much easier to prevent bad behaviors then to correct habitual bad behaviors, a lot of pet owners end up unknowingly creating bad behaviors in a puppy anyway. I want dogs in the shelter to be helped because I've seen dogs with so much potential.
