Here are some more likely reasons why a puppy might not wake up to be fed:
* Fullness: The puppy may simply be too full and not hungry.
* Sleep cycle: Puppies have very deep sleep cycles and may not be easily roused.
* Illness: A puppy who is sick may be too weak or uncomfortable to wake up.
* Stress or anxiety: If the puppy is in a new environment or experiencing stress, they may sleep more deeply.
What to do:
1. Observe the puppy: Look for other signs of illness or distress like lethargy, lack of appetite, vomiting, or diarrhea.
2. Try different methods to wake the puppy: Gently touch them, call their name, or offer a favorite treat.
3. Consult a veterinarian: If the puppy doesn't wake up or you're concerned about their health, it's crucial to seek professional advice.
Note: It's always best to consult a veterinarian to rule out any medical issues. They can also help you determine if your puppy might have hearing issues and recommend appropriate steps.
