This is how we understood providing sling support should be. If you have pictures to add, comments (even criticism, please post! This is how we learn).
Our understanding is a dog on 100% crate rest, needs support from the front and back ends. The front end a harness or collar (never a collar if it is a neck injury) is used to slow the dog down and prevent them from going more than a few steps. The back sling is to provide support to the back legs that are suffering from weakness or paralysis from the disc putting pressure on the spinal cord. You must support the back end at all times during the healing period. One bad slip can send you backwards in healing. Bear in mind this is for a male dachshund. Anatomically you will need to adjust where the sling is for a female.
Two points:
1) Never "wheelbarrow" the dog. You do not want to use the sling to lift the back legs up.
- The back should be completely flat.
- You are slinging for support!
2) As the dog gets stronger you can loosen the sling a bit, but you always want it under the dog for support.
- If they lose balance it is your job to make sure they don't fall.
If anyone else has any pictures of your dog using a sling while recovering, please post them.
