Osteochondritis dissecans is an inflammatory condition that occurs when diseased cartilage separates from the underlying bone. It most commonly affects the shoulder joint but the elbow, hip, or knee (stifle) may also be involved. This is a developmental disease that occurs in rapidly growing large breed dogs typically between 6 and 9 months of age and tends to occur more often in male dogs. Dogs that are affected with OCD typically limp or are lame in the affected leg or legs. Several radiographs of each affected leg are necessary to get an accurate assessment of various bones and joints. Treatment may involve conservative medical management or surgical intervention.

Osteochondrosis (OCD) is a failure of the bone underlying the smooth articular cartilage inside the joints, i.e. the subchondral bone, to form properly from the skeleton's cartilage template.

Osteosarcomas are somewhat rare in cats and progress slowly. Osteosarcoma is very painful. The most common location where osteosarcomas develop in cats is the hindlimb. Amputation is by far the most common treatment. Chemotherapy is not generally pursued without evidence of metastasis, given the relatively long-term control with surgery alone.

Osteosarcoma, or bone cancer, is common in large breed dogs and is very aggressive, with upwards of 90-95% of patients having micrometastasis. Osteosarcoma is very painful. Lameness or a distinct swelling may be noted. Amputation is by far the most common treatment with chemotherapy following surgery. Radiation therapy may also be an option.

Rarely, ovarian tissue can be left behind when a cat is spayed. This leads to the ongoing secretion of hormones such as estrogen and progesterone that can result in a cat continuing to have a heat cycle. Ovarian remnants are difficult to diagnose but vaginal cytology, combined with hormone testing, can be used to confirm the presence of functional ovarian tissue. Surgical treatment is typically recommended to prevent other health conditions from developing.

Ovarian tumors are quite rare in North American pets, mainly due to routine spaying practices. This handout discusses ovarian tumors in dogs and cats. The various forms of ovarian tumors, clinical signs, diagnosis, treatment, and prognosis of this cancer are outlined.

Some over-the-counter human medications can be used for common ailments in dogs, but you must consult your veterinarian before using them to determine the correct dose and to ensure they will not interact with other medications your dog is taking. Some medications are toxic. If the condition you are treating does not respond to treatment, contact your veterinarian.

Obesity is the most common problem in cats in North America and leads to an increased risk of diabetes mellitus, heart disease, and several types of cancer. Extra body fat causes increased inflammation associated with osteoarthritis. Reducing inflammation and pain can help an overweight cat to regain activity, which in turn can lead to more appropriate weight loss. Obesity can be prevented or reversed when cat owners are aware of calorie intake, body condition, and improving movement or activity.

Obesity is a common problem in cats. It results from too many calories being eaten and not enough calories being burned. Extra body fat causes increased inflammation in the body, worsening osteoarthritis and joint disease. To prevent your cat from becoming obese, speak to your veterinarian about your cat’s calorie needs and an appropriate food for your cat's life stage. Increasing your cat's daily activity can help prevent or reverse obesity. Be aware of your cat's body condition and keep track of her weight.
