Your dog will undoubtedly be hoping to return to its best as soon as possible.
There are times however when they require some help especially in the form of exercise.
You can start by keeping a short lease on your dog and signaling to them that they should gradually shift their weight onto their legs.
Rear support harnesses can also be used for this.
In addition to exercising on a treadmill or walking up steep slopes dogs can also strengthen their back legs by exercising in water.
