Instructions
Make a nesting box for the puppy. Use a box or bin that can be switched or cleaned easily. Place old towels or T-shirts in the box. Make sure the towels and clothing do not have holes or stray threads that the Yorkie puppies could become tangled in.
Put the heating pad under (not inside) one side of the nesting box so the puppy can crawl away from the heated side if it feels too hot. Hang the aquarium thermometer where it can monitor temperature, but out of the reach of the puppy. Set the heating pad to 75 degrees Fahrenheit, which is the appropriate floor temperature for 3-week-old Yorkies.
Feed the puppy four times per day, using replacement puppy formula and puppy nursing bottles. Hold the puppy upright and angled forward slightly on its tummy, not on its back like a human baby. Follow the feeding guide on the puppy replacement formula for how much to feed.
Begin to wean the puppy from the bottle. Put the puppy formula in a shallow pan, such as a cookie sheet, and place the puppy at the edge of the pan. Help the puppy find the formula and it should start lapping the formula. Alternate this with bottle feeding until the puppy easily laps from the pan.
Track the puppy's temperature. Most dog thermometers are rectal; follow the instructions for your specific thermometer. At 3 weeks old, the Yorkie's temperature should be between 99 and 100 degrees Fahrenheit. Contact your vet if the temperature is higher or lower.
Weigh the puppy using the food scale. By 3 weeks old, a Yorkie should be more than twice its birth weight. Contact your vet if the puppy is not gaining weight appropriately.
Stimulate the puppy's elimination of urine and feces using a cotton ball soaked in warm water. Gently rub the cotton ball on the puppy's genital area until it goes. By 3 weeks old, many Yorkies can go on their own. So do this only if the puppy is not urinating and defecating regularly on its own.
