I agree about something to protect his stomach while on steriods. Famotidine (Pepcid AC) is one option.http://www.dodgerslist.com/literature/I ... _used.html
Crate rest for spinal cord injury is perferred treatment. It allows swelling to go down in the injured area, and prevents making the injury worse. It helps function return quicker.
Perhaps a small fence to keep him in? When dragging around freely, the friction of grass and dirt will create an open sore on his hip or leg. This can attract flies that lay eggs in the wound. They grow into maggots, burrowing inside the flesh. It is called fly strike or myiasis. You may not notice it immediately, and it can be fatal.viewtopic.php?f=5&t=8702
If you do not have flies where you live, the sore can still develop a bacterial infection. Sores from dragging are very common. But the main reason for crating is to help the spine heal as well and as quickly as possible.
