将ScrollViewer放在DataGrid周围我还从DataGrid中删除了Width。

<Border Margin="30" BorderBrush="Blue" BorderThickness="2" Padding="10">
 <ScrollViewer HorizontalScrollBarVisibility="Auto" 
               VerticalScrollBarVisibility="Auto">
     <DataGrid ItemsSource="{Binding Source={StaticResource cvs}}"         
               ItemTemplate="{StaticResource animalTemplate}" 
               Name="ic" >
     </DataGrid>
   </ScrollViewer>
</Border>
