Vomiting is not a disease or disorder in itself; it is a clinical sign of some type of digestive disturbance or as a result of another disease or disorder. Occasional bouts of vomiting can be considered normal but if the vomiting persists and is accompanied by severe or bloody diarrhoea, lethargy, weakness, depression, pain or fever then this is a sign that something is seriously wrong and veterinary attention is required. Vomiting can be caused by something the dog has eaten (e.g. rotten food), ingestion of toxins, adverse reactions to drugs or an allergic reaction to something in the environment.
Regular socialisation and training, from as early as eight weeks of age, is an important factor in raising a well-behaved and socially acceptable dog. New puppy owners will benefit from enrolling their pups in a Puppy Pre-school class as soon as they bring their four-legged friend home. The RSPCA Pet Dog Manners class may also benefit your 4 legged friend!
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.
