A puppy is not self-cleaning. Dogs neither groom themselves nor clean up after themselves and, therefore, impose an additional workload on the household. A puppy is not a puppy forever . But they do need your love and care forever. Be sure you understand the commitment involved before succumbing to the charms of a cute, cuddly puppy.
Good breeders encourage questions.
If a breeder tries to intimidate you or makes fun of the questions you are asking, politely end the conversation. If the breeder claims they test their dogs, but can't find the certification papers or written results in order to provide a copy to you prior to the purchase of the puppy, politely end the conversation. If a breeder states that it's too expensive to test all of the dogs they breed, politely end the conversion. Walk away from all situations in which you are not comfortable. If you do, you may go home with a sickly, unsocialized or problematic dog, whose problems you will deal with for the rest of its life.
