Swimmer syndrome is a congenital disease of young pups characterized by weak limb development.
Clinically affected newborn pups classically present with turtle-like or walrus-swimming movements and may be associated with whelping onto smooth surfaces. There may be dorsoventral flattening of chest when only fore limbs are affected.
It may occasionally be associated with pectus excavatum but can be found in otherwise healthy pups.
Physiotherapy, particularly hydrotherapy, is recommended to develop full joint movement.
In most cases, euthanasia is not recommended as restoration of normal movement eventually occurs as the pup grows, provided the walking surfaces are firm such as carpet, grass, soil, etc.
