Puppies are cleaned and dry immediately after feeding. If they aren’t, the formula will start to harden, making it difficult to remove. Gently rub the puppies with a soft towel to remove any formula residue.


They don’t need a lot of space during their first week of life, as they will be spending most of their time sleeping. A small box or kennel will be perfect for them. Make sure the kennel is warm and draft-free, and place a heating pad or hot water bottle(around 85 degrees Fahrenheit) in it to keep the puppies warm.
