Why is my 6-month puppy crying and scratching door at night?

Poor Koko! The most common reason that puppies tend to cry at night, is when they are separated from their families - this often happens if they are crated in a different part of the house at night. Dogs are very social animals, and young puppies in particular would normally never be alone when they are sleeping - so they will often bark and cry if they are separated from you. I would recommend having Koko sleep in a comfy dog crate, right beside your bed. If needed, you can even place the crate on a low table or chair so that she is at eye-level with you - this way, she is in her own separate space but she can hear you and smell you beside her. This is also a good arrangement because it allows you to hear her if she cries to go out during the night - many puppies this age can't "hold it" for more than a few hours at a time, so nighttime potty trips are often needed for a while. Once she is older and sleeping through the night with no problem, you can gradually start to move the crate further away from the bed, or even eventually into another room if you prefer.

She is still very young and it will take her some time to learn to sleep through the night. You could try to put her crate next to your bed and see if that helps. You could also try an Adaptil Collar or Diffuser and Solliquin chews. https://www.adaptil.com/us/ http://www.solliquin.com/#page-top

At this age, if Mila wakes you up by whining in the middle of the night, I would take her outside for a potty break - she's too young to be expected to "hold it" successfully all night. Once she potties, bring her back inside and calmly put her back to bed. If needed, you can give her something like a Kong toy stuffed with peanut butter to keep her busy and help her settle again. As she gets older, she will eventually stop needing to go out during the night and will begin to sleep all night without waking up - just like a human baby :)

It is normal for a puppy as young as Bella to need to go outside once at night. I'd recommend taking her outside when she starts whining: make sure you go straight outside because you don't want her to think this is play time. If she does not urinate or defecate bring her back inside and out her directly in the crate. If she starts whining again do your best to ignore her until the morning. This is generally something she should grow out of as long as you are consistent.

I see that Rhea is still very young, only about 6 months old. I'm also not sure from your description if she is barking because she needs to go out and potty, or because she is anxious and lonely in her kennel. If she is needing to potty this often at night, I would be concerned that she may have a medical problem such as a UTI causing this - in that case, it would be best to take her to the vet to have this checked. If she doesn't need to potty but is just restless and upset in her kennel, I would first make sure that her kennel is in your bedroom - right next to your bed, if possible. It's not natural for puppies to be all alone at night, so many pups will cry if they are isolated in a separate room from their owners. Normally, moving her so that she is nearby resolves the problem - you can talk softly to her to reassure her if she wakes up and gets scared during the night.

If Sadie is urinating each time she goes outside overnight and urinating more frequently during the day this could be a sign of a urinary tract infection, which is not uncommon in a young female puppy. I'd recommend seeing your veterinarian who would likely check a urine sample for signs of infection. She may have also learned that if she whines to go out you'll wake up and she'll get a little play time so once you rule out a medical problem you may want to work on letting her cry for a bit in her crate before letting her out.

I would try putting Co co in a crate at night. Keep in mind she's quite young, and it will take time for her to adjust to being in a new home away from her mother and siblings. It's truly like having a newborn baby in the home! But the good news is that puppies will get better at sleeping at night faster than babies. If you are comfortable with it, you can have her sleep with you at night in your bed. That might make her feel more comfortable. I hope you get some sleep!
