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.
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.
