The key method to adopt here is one of positive reinforcement. Firstly, you need to show your pup the area where it should do its business, and each time the pup toilets in the designated area, immediately reward with a treat or verbal praise. In order to prevent mistakes from happening, it is important to both diligently supervise your dog while it is indoors and take it frequently outdoors. This will speed the learning process and prevent any accidents from occurring in the house.
It is important to note however that dogs who are never, or seldom allowed indoors, are more likely to become bored - and as a result become disruptive (e.g. bark for attention) and/or destructive (e.g. dig up your newly- planted rose bush). This is because dogs associate their human family as their pack and can develop behavioural issues if they feel neglected as a consequence of being excluded from interacting with their pack.
Male dogs are often quite independent and can be a little more difficult to train and control. Males also tend to wander and fight other dogs. Female dogs are more popular as family pets and may cost a little more. By nature females are affectionate and companionable, but unless desexed, will attract male dogs when in season and may reproduce every six months.
Puppy Roundworms can infect humans. To prevent this infection, puppies should be wormed regularly throughout their first year of life, and owners should be thorough with their own personal hygiene after having interacted with the dog. Tapeworms, Hookworms, and Whipworms can also infect dogs, and your veterinary surgeon can advise when to worm the dog.
