Take her temperature daily as her expected delivery date approaches. Normally a dog's temperature is between 101 and 102 degrees. When your pregnant dog's temperature drops below 100 degrees, that's an indication she'll have her puppies within 24 hours. Once labor begins, it can last up to 12 hours. If your dog's temperature drops significantly, she's ready to give birth soon.
Potty training can range from about 3-4 weeks to maybe a month, Depending on the breed, it can vary. An eager to please and intelligent breed such as a lab or collie should pick up on the pattern pretty quickly. Also having a schedule for the puppy to go outside is ideal. Picking up a routine for a puppy is almost as important as having a routine for a baby. Just keep at it! Potty training works best using a crate/kennel. During the day let your puppy roam around, take her out to potty outside several times. At night, put her in the crate and you dont take her out until you know you're ready to take her outside for her morning walk. Wait for her to do #1 and #2 and take her back inside.
