Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 1 year and 9 months old | 36 lbs
My dog has had about 3 episodes in the last week of violent shivering and heavy panting. He will be asleep then suddenly jump on my lap and lean on me. Usually his torso is hot to touch but his face and paws are cold. He acts like he's freaked out, he has his ears down and won't look at me. He refuses going outside or to let me move. I give him water and after about 20 minutes he goes back to sleep then it stops and he wakes up asks to go outside and then he's back to normal.

I can certainly see how this would be very alarming to witness. The symptoms you describe may be related to a disease process affecting an organ system (more often the neurologic (seizure event) or cardiac (heart event) systems). What i would recommend is a visit to your family veterinarian for a physical exam, to discuss the events, and to discuss additional testing (like bloodwork to rule out organ changes). It is also extremely helpful to get a video of an event so that your vet can watch it. Also, given the age of your pup, make sure there is nothing new in the environment that he could be snacking on that may be toxic to dogs (plants, etc.). I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
