Owners of active, athletic dogs sometimes seek out the help of their veterinarian because their pet is showing signs of exercise intolerance. These dogs may be underperforming compared with other dogs, or compared with their own usual performance standard.
Signs of exercise intolerance can be subtle, with suboptimal performance or movement difficulties noticed only by the dog’s owner or handler.
Alternatively, the signs may include profound exercise-induced weakness, episodes of collapse, or even death following exercise.
Please note the dvm360 article focuses on the conditions associated with exercise intolerance in retrievers. However, the conditions and principles of evaluating the problem in retrievers also apply to other breeds of dogs.
