Good Morning and welcome to Just answer. I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
There is a good chance that Milo is suffering from Vestibular Syndrome. This is a condition that affects the vestibular system so that he will become unstable on his feet. There often is no reason for this and it will resolve within 2 weeks. These are also signs of a stroke so it is good to have your vet examine Milo to be sure since a stroke would require treatment. If he is still eating well, this may be Vestibular Syndrome.
Here is a site that explains further....
