Intervertebral Disc Disease (IVDD)

seriousModerate
Typical onset:38 years

Degeneration or herniation of spinal discs causing pain and potential paralysis. Beagles have moderate risk due to their build.

Prevention: Maintain healthy weight, use ramps instead of stairs, avoid excessive jumping, support the back when lifting.

Symptoms: back or neck pain, reluctance to jump or climb, hunched posture, wobbling gait, paralysis in severe cases

Hypothyroidism
