Details
Affected dogs appear normal, and are capable of up to moderate exercise without incident. However, shortly after any strenuous exercise, they develop a wobbly gait with hindlimb weakness and incoordination, wide based stance, and walking with crouched hind legs. Signs can progress to full body weakness, extensor rigidity, and confusion. In extreme cases, it has been reported as fatal.
Details 2
Affected dogs have normal muscle mass, normal patellar reflexes before an episode of EIC, normal findings on muscle biopsy and are capable of moderate exertion without showing signs (Taylor et al., 2008, Patterson et al., 2008). Signs begin within 2 minutes after cessation of 5 to 15 minutes of strenuous exercise. Affected dogs develop a wobbly gait with hindlimb weakness and incoordination, wide based stance, and walking with crouched hind legs. Signs can progress to full body weakness, extensor rigidity, confusion, loss of consciousness, and rarely death. Episodes frequently last 5-10 minutes, often with complete recovery after 30 minutes. Loss of patellar reflexes persists after initial recovery.
