As many of you know, our dog recently tore his cranial cruciate ligament (CCL) and underwent tibial-plateau-leveling osteotomy (TPLO) surgery. I’ve since learned that this is an incredibly common condition. The surgery is expensive with a long recovery time, but it is a full recovery in the majority of cases.
Dogs who have this surgery are likely to experience tears in their other legs. Mobility is limited during the recovery process, causing muscles and ligaments to weaken. Therefore, I’ve been researching things that I can do–and it turns out that there are many–to prevent future CCL tears and boost overall health.
My partnership with Petcurean grants access to experts so I thought I’d ask Dr. Jennifer Adolphe, Petcurean’s Senior Nutritionist, about the role diet plays in joint and ligament health. As a registered dietitian, Jennifer began her career in human nutrition, but in 2009 she decided to combine her interest in nutrition with her love of animals and pursue a PhD in pet nutrition.
Before asking these questions, I had no idea that Dr. Adolphe’s own dog experienced a CCL tear. See what I mean by common?
What is the CCL?
The cranial cruciate ligament (CCL) is a ligament in the knee (stifle) joint that connects the femur (thigh bone) to the tibia (shin bone) to stabilize the joint.
One of my own dogs, an Australian Shepherd named Timber, suffered from a CCL tear a couple of years ago for which he underwent tibial tuberosity advancement (TTA) surgery. Unfortunately, Timber subsequently had damage to the stifle joint meniscus, a post-surgical complication that happens in a small percentage of TTA patients. However, I am very happy to report that he has fully recovered and at 10 years old, can still keep up with dogs half his age!
What role does a dog’s diet play in preventing or treating CCL tears?
Cruciate ligament tears tend to be more common in medium to large breed dogs. Nutrition during puppyhood is especially critical for large breed dogs to ensure proper bone and joint development. Large breed puppies should be fed a complete and balanced dog food formulated for growth of large breeds for the first one to two years of life. Puppies should be portion-fed, not free-fed, to prevent high calorie intake and maintain a lean body condition. Excessive energy intake in large breed puppies promotes a high rate of growth and can contribute to abnormal skeletal development, which may predispose to musculoskeletal injuries.
In addition, excessive calcium intake has been shown to result in abnormal bone development. The Association of American Feed Control Officials (AAFCO) has recently published revised calcium requirements which have reduced the maximum calcium content of dog foods suitable for large breed puppies from 2.5% to 1.8% calcium on a dry matter basis.
Excess body weight can exacerbate joint disease and increase the likelihood of CCL injury. Ensuring your dog achieves and maintains a healthy body weight is one of the most important things you can do to help your pet live a long, healthy life. A body score chart can help you determine if your dog is at a healthy body weight. If your dog needs to lose a pound or two, reduce the amount you feed gradually until you achieve a modest rate of weight loss of 1-2% per week. Weigh your dog’s food using a kitchen scale rather than using a measuring cup or free-feeding since weighing is much more accurate. While every dog deserves an occasional treat, be careful not to overfeed treats as the extra calories add up quickly.
Are there specific foods to avoid?
There are no specific foods to avoid to prevent or treat CCL tears. Choose a high quality, complete and balanced dog food to meet all of your dog’s nutrient requirements. When choosing a food, consider your dog’s health, age, breed and lifestyle. If your dog has a dull coat, upset stomach, ear infections or persistent scratching, it may be time to consider switching foods. A food that works well for one dog, may not work as well for another dog. Petcurean’s food finder is a great place to start if you need a little bit of help choosing a suitable food for your dog.

Which supplements do you recommend for dogs with this condition?
Speak with your veterinarian about which supplements may be helpful for your dog. Dogs that have had a CCL tear are more prone to arthritis in the stifle joint. Some examples of supplements that may be recommended for joint health include glucosamine, chondroitin, green lipped mussels, natural eggshell membrane and omega-3 fatty acids. Many complete and balanced pet foods contain one or more of these supplements.
Achieving and maintaining an ideal body weight is important for dogs who have had a CCL injury to help prevent damage to the other stifle joint. L-carnitine and a diet that is higher in protein and fiber may help to promote weight management.
What other changes can pet owners make for dogs who are recovering from CCL tears?
Nutrition is an important part of aftercare for any surgery to provide the energy and essential nutrients that the body needs for tissue repair and recovery. In the immediate post-surgery state, follow the recommendations of your veterinarian for reintroducing food. If your dog’s appetite has been impacted by the surgery, try adding some canned food or low sodium broth to his usual kibble to help entice him to eat. Based on my own experience with Timber after his CCL surgery, patience and adherence to the rehabilitation plan provided by your veterinarian are key factors to a successful recovery.
