Surgery for dogs, as with humans, is a final alternative when non-invasive methods are unable to treat a condition, since they are irreversible and carry risk.
Conditions such as hip dysplasia and arthritis can often be treated with appropriate medications that help the body handle pain, inflammation, or joint wear and tear.
However, this is a major surgery taking several months to fully recuperate, involving the large muscle groups of the hips, and is irreversible.
Whilst it has a high success rate (circa 95%) in the hands of a good surgical team, even in older dogs, it is therefore often recommended to avoid it until quality of life is seriously affected beyond the capability of medication to control.
Thus the benefits of hip replacement at a younger age must be set against the risks and the existing quality of life attainable with medication, lifestyle change, or non-surgical handling.
The animal must also be kept away from slippery or smooth flooring such as tiles, marble or polished wood since these put considerable lateral (sideways) strain on the hips.
This ensures that there is always the maximum natural support during the healing process, although bilateral (double) hip replacements are possible and can be performed if appropriate.
