My new puppy shakes while sleeping with eyes open. Is this normal?
If he is otherwise normal I'm not concerned. He may be stressed from moving to a new home or dreaming. If it was a seizure you would notice him going from normal to having muscle spasms, then getting back to normal in a few minutes. It's a good idea to video the behavior and write down when it occurs so you have a history to discuss with your veterinarian should it get worse. I like to write down the episodes on a calendar so I can go back and check the frequency. Willis may stop this as he becomes settled in your house and as he gets older. If he appears agitated, weak or ill please take him right in for an exam. You may want to double check with his breeder to see if any other pups or the parents are doing this. Cavaliers do get heart disease, but usually when they are old, and purebred dogs can get epilepsy but seizures often don't start until they are six months to a year old. Again I would just watch him to make sure there are no other symptoms. Enjoy your new puppy! I love Cavaliers, it's a fun, gentle and loving breed. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Willis.
