What a beautiful boy you've got there. You can see the love and gentleness in his eyes It's the hardest thing, to see our 4 legged friends in distress. From what you have said, Rex is still enjoying life and craving the comfort and companionship of his devoted guardian and best friend. Is the vet sure he had a stroke and is not having seizures? Seizures could possibly be controlled with medication. I'm not sure how invasive the tests are that he mentioned. I believe an MRI would most likely confirm a stroke. And while not painful or invasive, it could probably stress Rex. As long as he seems happy, is enjoying eating and is drinking, and is in otherwise good health, I would continue as you are, enjoying each and every day together to the fullest. My thoughts are with you and your beloved best friend. {{{HUGS}}} Sandra
