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.
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.
