Every new pup should be taken to a veterinarian for a thorough check-up and a series of shots against common virus diseases such as canine distemper, hepatitis and leptospirosis and kennel cough. At a later age, the pup will need a rabies vaccination, and depending on where you live, a blood test and regular preventive medication against heartworm. Until your vet says that your dog is safely protected by the vaccinations she was given, do not take your pup out on a leash or to the park to play with other dogs, or she may succumb to a serious infectious disease from another dog. Pups are usually born with roundworms and sometimes hookworms, for which they should have their stools examined.
Many people make the mistake of worming their pet whenever it seems to be sick.
This can be dangerous, as real symptoms get overlooked. Avoid all home-doctoring except under your vet's instructions. Adult dogs will often get infested with hookworms, especially if they're kept outdoors. These worms develop in the soil and then get into the dog by burrowing into the skin, from where they migrate to the dog's intestines. Regular check-ups are extremely important to control this parasite.
