Q. We just adopted a Lab puppy who seems to be hungry all the time. She is usually awake by 4:30 am. Wondering on when and how much to feed her?
A. It depends on the food you feed her. Read the back of the bag of food, whatever it says on the back under "amount for puppy", decrease that by a very small amount. Often kibble bags encourage overeating to sell more product.
You should be feeding the puppy at three set times throughout the day. A nice and early breakfast, lunch, and dinner. Make sure you aren't feeding too close to bedtime. Give the puppy an hour after eating before bed in case she has to eliminate outdoors again before bed.
I'm wondering if maybe she's just waking up at 4:30am to be taken outside to eliminate. Puppies can typically only hold their bladders 1 hour per month of age, plus 1.. and that's typically pushing it until after 6mo of age. Have you tried just bringing the puppy outdoors, and then luring her back into her crate with a high value treat? See if she'll go back to sleep.
