Arthritis and dogs

Osteoarthritis (also called arthrosis or arthritis) and dogs

Osteoarthritis is very common in older dogs: All shapes, sizes, and breeds can be affected, but some breeds, like German Shepherd Dogs or Labradors are particularly prone. Large and giant breeds are also known to have more severe symptoms or to get osteoarthritis earlier.

The destruction of the cartilage usually occurs in two circumstances: normal physical pressure on abnormal joints, or abnormal physical pressure on normal joints. For example, dogs with a history of joint instability are more likely to get severe osteoarthritis later in life.

Instability, uneven weight distribution around the joint and injury to the joint are the major factors that predispose dogs to arthritis or hip dysplasia (abnormal regrowth of the cartilage in the hip).
Orthopaedic surgery and fractures involving joints are a few examples of possible predisposing causes.
Obesity, which is very common in sedentary dogs, also significantly contributes to the development of arthritis.

• While standing, the dog's back legs are held closer together, so its weight is shifted to its front legs
• "Bunny hopping", when the dog runs with both hind legs together
• Reluctance to walk, climb stairs, jump, or play
• Lameness
• The dog walks slower than normal or there is a change in gait
• A slight limp
• Difficulty sitting or rising from a resting position
• Yelping in pain when touched
• Seeming to have stiff or sore joints
• Attitude or behaviour changes
• Being less alert
• Sleeping more
• Weight gain
