As a dog owner you are fully and legally responsible for any harm or damages caused by your dog. If your dog bites a human, kills wildlife, damages property, causes a traffic accident, creates noise or other pollution, or is the direct cause of any other damage to the community, you may have to shoulder a substantial financial (if not legal) penalty. It is in your best interest then to always keep a vigilant eye on your dog in public and provide him with the obedience training and socialisation skills necessary to become a well-mannered and socially well-adjusted dog.
Diarrhoea is similar to vomiting in that it is a clinical sign rather than a disease itself. Diarrhoea can be a sign of a mild digestive upset or of something more serious e.g. food poisoning or ingestion of other toxic materials. Acute and chronic diarrhoea can be life threatening, particularly in puppies or older dogs. If the diarrhoea lasts longer than a couple of hours, contains blood and the dog appears to be in pain and has a fever then veterinary attention is required immediately. Treatment in this case will include identification and appropriate treatment for the underlying condition causing the diarrhoea as well as fluid and electrolyte therapy. Mild cases can be treated at home by removing food for a period of 12 hours and then re-introducing small amounts of bland food (e.g. chicken and rice). Probiotics can also be a useful addition to improve the overall health of the affected dog’s intestines.
As mentioned above, puppies respond well to positive-reinforcement based training. It is important to acknowledge that dogs cannot possibly know which behaviours are right and which are wrong - it will be up to you to teach them. Take the time to show your puppy what you want them to do and reward them with a treat, praise, or a game each time they do the right thing.
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.
However, if you decide to keep your dog outdoors, it is important to consider how you'll ensure it receives the appropriate amount of human contact (particularly during those cold winter months in which we'd all much rather stay snuggled inside rather than playing fetch with our pals in the cold!). An option could be to enlist the service of a dog walker. Also, if you work long hours or are sometimes forced to take overnight trips, it may be useful to consider "doggy day care" facilities to ensure that your dog receives the TLC and companionship it will need in your absence.
If your puppy is behaving inappropriately you should attempt to re-direct them to something else and reward them when they begin to engage in more appropriate behaviour. For example, if your puppy is chewing on the furniture, re-direct him to an appropriate alternative such as a chew toy. Alternately, you may find that ignoring the undesirable behaviour and rewarding the correct one can also be a very effective way to train your puppy.
Lungworm larvae may be present in slugs and snails, and if eaten, pets may be infected with worms that make their way to the lungs, where they block airways and make breathing difficult. Most dog wormers don't claim to treat lungworm, although some cat wormers do. Research conducted internationally has found moxidectin, which is found in some heartworm treatments for dogs, to be effective against lungworm, but this claim can't be made for dogs on packaging in Australia. Check with your vet as to whether it's an issue in your area, and discuss the best preventative treatment.
