There is one 35 days old puppy who shivers after eating can I share video for differential diagnosis ?

Yes, absolutely! Please go ahead and share the video. I'll analyze it to help build a differential diagnosis list for the shivering in your 35-day-old puppy after eating.
A few quick notes while you upload:
Common differentials for post-prandial shivering in a 35-day-old puppy:
  • Hypoglycemia - very common at this age; blood sugar drops can cause tremors/shivering
  • Hypothermia - neonates poorly regulate body temperature, especially post-feeding
  • Portosystemic shunt - post-meal toxin load causes neurological signs
  • Cerebellar hypoplasia - intention tremors, often worsened by activity/eating
  • Distemper - myoclonus/tremors are classic signs
  • Pain/discomfort - GI distress, bloating post-feeding
  • Electrolyte imbalances - hypocalcemia, hypomagnesemia

Once you share the video, I can analyze the character of the shivering (coarse vs. fine, focal vs. generalized, persistent vs. episodic), posture, gait, and any other signs visible - which will help narrow this list considerably.
Please upload the video and I'll get started right away!
