Are Corgis Prone to Patellar Luxation?
Corgis are indeed a high-risk breed for patellar luxation. Data from the Orthopedic Foundation for Animals (OFA) puts corgis in the top three among small breeds, with about 20%–30% developing some degree of the condition. The cause is twofold: a genetic mutation that leaves the trochlear groove too shallow to hold the kneecap, and a short-leg bone structure that angles the femur and tibia inward by 15°–20° more than usual, pushing the patella out of place. The problem is graded I–IV, from occasional skip-hopping to permanent dislocation. Mild cases are managed with joint supplements and limited exercise, while grades III–IV usually need surgery. Keeping the dog at a healthy weight and avoiding stairs and jumping are the best prevention.
Common Bone and Joint Diseases in Dogs
Poor care often deforms a dog's legs. Know the risks: hip and elbow dysplasia in retrievers and shepherds, osteochondrosis in large fast growers, femoral head issues in small breeds, and degenerative joint disease eased by weight control, gentle exercise, and glucosamine. Home setup matters too, slippery floors and stairs cause lasting damage.
Chondrosarcomas in Dogs and Cats
Chondrosarcoma is a malignant bone tumor from cartilage cells, second only to osteosarcoma in frequency. It favors flat bones such as ribs, nasal bones, and pelvis and is seen more in German Shepherds. Outlook is guarded even with surgery.
Chondromas in Dogs and Cats
Chondromas are benign cartilage tumors that arise in the long bones and affect the ribs, pelvis, and sternum. They are attached to bone and need surgery only when swollen or pressing on a nerve. Most cause no signs and need no treatment.
Osteosarcomas in Dogs and Cats
Osteosarcoma is a malignant bone tumor from abnormal osteoblasts, most common in large and giant dog breeds. The main sign is lameness, with swelling, pain, and possible pathological fracture. Early limb amputation plus anti-cancer medication is standard, but the outlook is poor.
Osteomas in Dogs and Cats
Osteomas are common benign bone tumors formed from bone tissue, often linked to exostoses, injury, bone inflammation, or nutritional disorders. They usually cause no signs unless they press on a nerve or organ. Surgery is used when the site allows, and amputation for malignant limb tumors.
Torticollis in Dogs and Cats: Symptoms, Treatment, and Prevention
Torticollis is a head tilt or twist from neck-muscle spasm or paralysis, cervical rheumatism, vertebral dislocation or fracture, neuritis, or ligament injury - often after a fall, blow, or tight collar. Ear infection can also cause it. Treatment targets the underlying cause, with rest, pain relief, and, for fractures, cervical stabilization.
Degenerative Arthritis in Dogs and Cats: Symptoms, Treatment, and Prevention
Degenerative arthritis (osteoarthritis) is non-suppurative wear of joint cartilage from years of uneven load, more common in older pets. It causes pain, stiffness, limited motion, and lameness that worsens with activity and cold weather. Weight control, controlled exercise, pain relief, and surgery in severe cases manage it.
Suppurative Arthritis in Dogs and Cats: Symptoms, Treatment, and Prevention
Suppurative arthritis is infection of a joint by pyogenic bacteria, either carried in the blood or introduced through a penetrating wound, causing hot, painful swelling, fever, and lameness. Prompt drainage and antibiotic therapy are essential to save the joint and prevent spread; untreated it can rupture through the skin.
Multiple Cartilaginous Exostoses in Dogs and Cats: Symptoms, Treatment, and Prevention
Multiple cartilaginous exostoses (multiple osteochondromas) are benign bony outgrowths that can appear on the spine, ribs, and long bones of young dogs and cats, possibly inherited. They are painless until they press on a tendon, vessel, or nerve, causing lameness, pain, or incoordination; otherwise no treatment is needed, but symptomatic ones are removed surgically.
