Your puppy may not be able to sleep through the night until they are 16 weeks old. Around 4 months. The mother normally spends most of her time with the puppies, so make sure to see the puppies breastfeeding at least once a day. He certainly loved cuddling up with him, and even after he went on to sleep out of the box once he was old enough, he still carried the Snuggle Puppy puppy around to use as a pillow, as can be seen in the inserted photo.
Cage training is useful for making puppies feel more secure and helps with training at home, as well as getting puppies to sleep. So, even if your pup sleeps through the night, they'll need plenty of naps throughout the day to recharge their rest, so it's important to let dogs sleep. A good rule of thumb is that puppies can generally hold their urine for their age in months plus one, converted to hours. Try to start slowly, giving puppies solid food that has been heated and moistened with a little water.
Keeping track of your puppy's potty can really help you determine your puppy's natural potty schedule, which can help you adjust feeding times to increase sleep time at night. Paying too much attention to your puppy in the middle of the night can cause him to wake you up just to attract attention, even if he doesn't have to urinate. Teena Patel, a dog trainer and owner of the Doglands' University training center, says puppies wake up so often because they feel lonely for their mothers. In addition, puppies don't know when to stop sometimes and will continue to play when they should take a nap, so take them to bed if they show any signs of fatigue.
At eight weeks of age, most puppies can eat well, no longer need to breastfeed or eat supplemental formula, they are mobile and know their world. When they are awake, puppies burn a lot of energy: they grow physically, experience new people and places, learn what they can and cannot do. The traditional age for puppies to leave their mother and litter mates and go to their new home has been eight weeks old. Some puppies do better with a full view of their surroundings, but I have found that most prefer a cage more like a den.
It will probably take a few weeks before your puppy starts sleeping through the night, and to do so, you need to help your puppy develop a healthy sleep routine. Puppies will continue to eat until they are full, so there is no need to remove the bottle unless they start coughing or milk comes out of their nose.
