A non-compressing disc protrusion to me just means it&rsquo;s bulging but not compressing neural structures, i.e. insignificant. I don&rsquo;t know what is happening here but acute onset ataxia in a dog of this breed and age immediately makes me consider a cerebrovascular accident. If this dog had a cerebral infarction&nbsp;then it will be improving now so fits with clinical picture. I&rsquo;d not worry about managing any differently and encourage the owner to returnee dog to normal exercise as soon as it is able to. </p><div style="clear:both;"></div>
