Swimming has long been recognized as one of the best forms of physical activity for humans and it is no different for dogs. Due to the weight bearing properties of water it is possible to exercise without putting impact stresses on joints, particularly important if a dog is suffering from arthritis or similar complaint or recovering from injury.

The hydrostatic pressure exerted by being immersed in water provides an improved environment for working with swollen joints, it opposes the tendency for blood to pool in the lower portions of the body and so can aid in reducing swelling.

Because of the viscosity of water the increased resistance to movement can strengthen muscles and improve cardiovascular fitness
