How to help your puppy stop barking at night:
* Create a calming bedtime routine: Feed them dinner, take them for a last potty break, and then settle them in their bed with a safe and comforting chew toy.
* Ignore the barking: Avoid reinforcing the barking by responding to it. If you acknowledge it, the puppy might learn that barking gets attention.
* Consider a crate: A crate can provide a safe and secure space for your puppy, especially if they are feeling anxious. Make sure the crate is big enough for them to stand up and turn around comfortably.
* Seek professional help: If your puppy's barking is severe or persistent, it's best to consult with a veterinarian or certified dog trainer. They can help you rule out any medical causes and provide you with personalized advice and training strategies.
Remember, puppies are still learning and adapting to their new environment, so patience and consistency are key!
