Keep basement doors and upper-story windows closed. Don't invite other pets to your house until your puppy is fully vaccinated. A puppy's resistance to infection is lower than an adult dog's until about 16 weeks of age. Dispose of chicken and turkey bones in a puppy-proof manner. Puppies like these bones and will search through the trash to get them.
Small bones can be life-threatening.
Don't leave needles or pins out where the puppy can get to them. Puppies often swallow them. Avoid using flea collars and flea dips until your puppy is at least 15 weeks old. Find out the limitations of flea products before you apply them.
