Most poisoning of dogs is accidental. Garden poisons, such as snail baits, are the main cause. If your dog is known to eat just about anything, then be particularly careful to store poisons where they will not be accessible to him. Dogs found foaming at the mouth, with muscle tremors or staggering gait, or unable to stand, should receive immediate veterinary treatment.
There are various intestinal worms that can infect dogs and cats, with hook worms, round worms (ascarids), whip worms (mainly in dogs) and tapeworms being the main groups. Symptoms can include diarrhoea, bloody stools, weight loss, anaemia, pot belly, dry hair and/or general poor appearance. If left untreated, worm infestations can be fatal. Worms can be picked up from the mother (either in utero or via milk), from the environment (infected stools), from eating infected prey (lizard or mouse), or, in the case of tapeworms, from fleas. Worms can also be transmitted to humans.
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.
Pedigree or purebred dogs are more expensive to buy if purchased from a breeder and their nature and appearance is generally predictable (as they should conform to a breed standard). Crossbreeds (or 'designer dogs') are dogs of mixed ancestry. They are robust and often make great pets. Keep in mind though, that when you purchase a crossbred puppy it might be difficult to accurately predict how these puppies will develop. Both purebred and crossbred puppies and adult dogs are available at RSPCA Adoption Centres.
If dogs live indoors they need to be provided with a dog bed. Most dogs though are hardy enough to sleep outdoors in a well-built, well-furnished and weatherproof kennel. The kennel should be warm, dry and draught free, elevated from the ground, near the house and human activity but not in a thoroughfare. It should be protected from rain and excessive sun, and the bedding should be changed regularly. Washable rugs, cushions or blankets are suitable as bedding.
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.
Combing and brushing dogs regularly is essential, particularly for longhaired breeds. It is best to establish this habit early in a dog’s life so that grooming becomes part of the routine. Grooming removes dust, dead skin, loose hairs, grass seeds, and tangles. It also assists to shorten the coat moult, which occurs every autumn and spring. Brushing helps keep your dog cool in summer months and reduces the amount of hair your dog sheds. Dogs with short coats also require some brushing.
