Canine / 狗: Patellar luxations (knee cap) 膝關節移位


一般因為骨骼角度不正確及不夠深導致膝蓋骨很容易就脫離位置這會鎖定腿部引致腳 離地.

What is Patellar luxations?
Usually the ridges forming the patellar groove are not prominent, the patella will luxate (jump out of the groove) sideways, especially toward the inside. This causes the leg to 'lock up' with the foot held off the ground.  

  • 跑的時後會有時跳
  • 不願行動
  • Skip while running
  • Unwilling to move

What breeds are affected? 一般受影響的狗

  • Exercise your dog appropriate to help build muscle to support the joint
  • If you have dogs with this issues, please do not breed them
  • Trimming toenails to prevent any snagging that could cause trauma to the knee
  • Feeding dog with glucosamine and chondrotin supplement to help provide some extra relief to the dog’s knees and to help slow the acceleration of arthritis (see other ways to help relieve Canine - Arthritis and Joint Supplement / 關節補充品)
  • Feeding omega-3 such as Coat Plus to help reduce inflammation. 
  • Surgery is the only option that will fix it for a long term.  Speak to your vet to find out the grade of the knees.
