Ask a Dog Vet and Get Answers to Your Dog Veterinary Questions
Hi this is Dr. Gabby,
Usually if they are dragging their hind legs after a collision there is a back injury. There are spongy discs between the bony vertebrae. If injured the disc material can bulge out or completely herniate out. This causes abnormal pressure on the surrounding nerves and spinal cord. That causes the legs to drag because the nerve or spinal cord signals are not going through.
He definitely needs to see a vet. The treatment may be cortisone and strict rest. Muscle relaxers may be prescribed as well.
Until you can get him to a vet you can give him aspirin. It has to be aspirin and nothing else. 5 mg of aspirin per each pound of dog every 12 hours. Give it with a meal to help prevent gastrointestinal upset.
Keep him confined. If he moves around he could further damage his spinal cord and become paralyzed.
Carry him out to go the bathroom.
If you are not planning on adopting him as yours I would take him to the humane society or maltese rescue.
Do a google search "maltese rescue and the state you live in."
I was an SPCA vet for three years and the little dogs get adopted more frequently.
If you are going to be his new home that is great and he is lucky to have you.
Does that help? Do you have any additional questions?
