One of the most common injuries that dogs experience is a torn ACL, which stands for anterior cruciate ligament. The cruciate ligament stabilizes a dog’s knee joint and keeps the bones from moving out of place.
When it tears, it can cause your dog’s knees to feel pain and lose mobility. In many dogs, an ACL tear occurs because of a sudden movement or over-exertion, such as when playing fetch or jumping off something.
Importance of Understanding the Condition

Knowing about an ACL tear is essential for a pet owner because it can help you recognize when your dog may be injured and need medical attention. Additionally, understanding how the injury occurred can help you take preventative measures to avoid future injuries. If left untreated, an injured leg could lead to further complications such as arthritis or other knee problems.
Recognizing symptoms early on and getting proper treatment can prevent more severe issues from developing. Many dogs are prone to tearing their cruciate ligaments due to genetics or breed tendencies.
While larger breeds tend to be more susceptible, smaller dogs are also at risk if they have weak joints due to either genetics or injury. In this article, we will discuss the symptoms of a torn ACL in small dogs,, diagnosis, and treatment options, including non-surgical methods like joint supplements and physical therapy as well surgical treatments like TPLO surgery, along with recovery times for all options available. Crucial points on prevention strategies will also be discussed so that you can keep your furry friend healthy and happy by avoiding weekend warrior syndrome while maintaining their healthy diet too.
What is an ACL Tear?
The Anatomy Involved

The anterior cruciate ligament (ACL) is one of the four major ligaments stabilizing the dog’s knee joint. The ACL connects the thigh femur bone to the lower leg’s tibia bone. It plays a crucial role in maintaining normal function of the dog’s knee joint as it prevents forward movement of shin bone and the tibia and rotation of the lower leg bone.
How it Happens, and Common Causes
Torn ACLs are common injuries in dogs, especially in larger breeds. A sudden and unexpected change in direction while running or jumping can cause this type of knee injury and trauma or hyperextension to the knee joint. In smaller dogs, jumping from high surfaces can also result in a torn CCL (cranial cruciate ligament – another name for ACL).
Some dog breeds also are more prone than larger dogs to getting torn ACLs due to genetics, structure, and other factors such as obesity, age, or degeneration from previous injuries. Many dogs with this type of injury will have a positive cranial drawer test indicating abnormal knee joint movement.
If left untreated, a ruptured ACL can lead to instability and arthritis, which can be very painful for your furry friend. If you suspect your dog has an ACL tear or any other knee injuries, it’s important to bring them to their veterinarian immediately for proper diagnosis and treatment options.
Symptoms of an ACL Tear in Dogs: Limping or Lameness

One of the most common symptoms of a torn ACL in dogs is limping or lameness in one or both hind legs. Many dogs shift their weight to the front legs to avoid putting pressure on the injured leg, causing an uneven gait. You might also notice that your dog is reluctant to put weight on the affected hind leg or hesitant to jump up onto furniture or climb stairs.
If you suspect your dog has an ACL injury, bring them to a veterinarian for a consultation. A positive cranial drawer test is one-way vets diagnose this type of injury.
This test involves moving the tibia bone forward while holding onto the thigh bone and observing how much movement there is between them. If there is too much movement, it could indicate a cranial cruciate rupture.
Difficulty Standing Up or Lying Down
Another symptom of a dog’s ACL injury can be difficulty standing up or lying down. This can happen because the knee joint is unstable and causes discomfort when moving around.
You might notice that your pet struggles when getting up from a lying position and may even use their front paws to push themselves up. If you see any signs of difficulty moving around, take your dog’s injury seriously by talking with your vet about what’s next for their recovery process so it’s done properly and safely for both pet owners and pets.
Swelling Around The Knee Joint
A torn ligament in dogs often causes swelling around the knee joint, which indicates inflammation caused by a fluid buildup within tissues due to damage during the injury pain associated with this type of swelling can also cause redness and warmth in the area where tissues were damaged. It could cause infections if not treated properly!
Pet owners should look out for this symptom and immediately bring their dog to the vet. Depending on the severity of the injury, vets may recommend surgical procedures or rehabilitation therapy.
It’s important to note that small dogs are more susceptible to ACL tears than larger breeds due to their relatively weaker bones and joints, so make sure to avoid “weekend warrior syndrome” and take precautions when exercising your furry friend. Joint supplements can help maintain joint health and prevent future injuries as well.
Diagnosis and Treatment Options
Physical examination by a veterinarian

If your dog is showing symptoms of an ACL tear, such as limping or not wanting to put weight on their hind leg, it’s essential to take them to the vet for a physical examination. During the exam, the veterinarian will check for signs of an ACL injury, such as a positive cranial drawer test. This involves manipulating the knee joint to see if any movement shouldn’t be there.
They may also palpate the joint and surrounding tissues to check for swelling or pain. If the vet suspects an ACL tear, they may recommend further testing.
X-rays and other imaging tests
To confirm a diagnosis of an ACL tear, x-rays or other imaging tests may be necessary. X-rays can show if there are any bone abnormalities or fractures in the knee joint that could be contributing to your dog’s symptoms. Other imaging tests, such as an MRI or ultrasound, can help visualize soft tissue injuries like torn ligaments.
Non-surgical options such as rest, medication, and physical therapy
In some cases where the injury is mild or your dog is not a good candidate for surgery (such as older dogs or dogs with other health issues), non-surgical treatment options may be recommended. This can include rest to allow scar tissue around the injured ligament time to heal independently, pain medication to manage discomfort during recovery, and physical therapy exercises.
Surgical options such as TPLO, TTA, and extracapsular repair
Several surgical options are available for more severe cases of ACL injuries in dogs where your veterinarian recommends surgery, including TPLO (Tibial Plateau Leveling Osteotomy), TTA (Tibial Tuberosity Advancement), and extracapsular repair. The type of surgery recommended will vary depending on the severity of the injury, your dog’s size and breed, and other factors. Surgery is typically followed by rest and rehabilitation to help your dog’s recovery.
Working closely with your veterinarian is important to determine the best treatment for your dog’s ACL injury. Many dogs can fully recover and return to normal activities with proper care and management.
Recovery Process for Dogs with an ACL Tear
Postoperative care and rehabilitation

After the ACL surgery has been performed on your furry friend, rehabilitation begins. Giving your dog enough time to recover from the surgery is essential before starting any physical therapy or exercise routine. This means limiting their physical activity and keeping them calm while they heal.
A veterinarian may recommend a stay in a specialized recovery facility, where the dog will receive 24-hour care and attention. Once your dog’s initial recovery period has ended, starting them on a rehabilitation therapy program as soon as possible is essential.
This includes regular exercise routines that can help rebuild strength in their injured leg and knee brace. Physical therapy can also strengthen muscles around the knee joint and help prevent further injuries.
Timeline for Recovery
The timeline for your dog’s recovery after an ACL surgery varies based on several factors, such as age, weight, overall health condition, and how well they follow postoperative instructions from their veterinarian. However, typically dogs need six months of postoperative care to achieve normal function.
You must be patient and keep your expectations realistic during this time frame. Your dog’s recovery may seem slow at first but don’t worry; with time and proper care from you at home or a specialized facility followed by regular checkups with your vet will ensure that your furry canine companion never returns to its pre-injury form.
Potential complications to watch out for
While surgical repair is often successful in healing an ACL tear in dogs successfully; there are possible complications that pet owners should be aware of during their dog’s recovery process after surgical procedure. One potential issue is scar tissue buildup around the knee joint which can lead to permanent loss of function if not addressed promptly by a vet skilled in canine orthopedics. Another complication is bone cancer, which can occur in dogs with a history of ACL tears.
This issue should be addressed early on if it is suspected. Obese dogs may have more difficulty recovering from ACL surgery because of their weight and subsequent pressure on the injured leg.
It is crucial to watch for any unusual behavior or signs your dog may display during recovery. If you notice anything unusual or worrying, contact your veterinarian immediately to ensure your pet’s complete recovery.
Prevention Strategies for Future Injuries
Exercise Routines That Can Help Prevent Injuries to the ACL
As a pet parent, you want to maintain your dog’s health and fitness. One of the ways you can do this is by engaging in exercises that help prevent injuries to your ACL.
These exercises are essential for large breed dogs prone to developing torn ACLs, such as small and overweight dogs. One exercise routine vets recommend large breed dogs is a slow jog or walk on soft surfaces such as grass or sand.
It helps strengthen the muscles around the knee joint but also helps improve your dog’s overall fitness level. Additionally, doing hill work with your dog can help build strength in their legs.
Another exercise routine recommended is swimming. Swimming has low-impact movements and can provide excellent cardiovascular exercise while building muscle strength without stressing your dog’s joints.
Diet Recommendations to Maintain a Healthy Weight
Maintaining a healthy weight is crucial in preventing your dog’s ACL injuries. Overweight dogs have increased pressure and strain on their joints, which makes them more susceptible to tearing their cruciate ligament. A balanced, healthy diet, rich in lean protein, whole grains, fruits, and vegetables can help maintain a healthy weight for your dog.
Avoiding high-fat foods for large dogs such as table scraps or fatty meats will help reduce excessive body fat in your furry friend. To ensure that your dog gets all the necessary nutrients for optimal health, consult a veterinarian about what types of food best suit their needs.
Maintaining an active lifestyle in dog breeds through regular exercise routines and feeding healthy diets are essential to preventing injuries like torn cruciate ligaments in dogs. By following these prevention strategies diligently and getting regular checkups from veterinarians who specialize in orthopedics like Tibial plateau leveling osteotomy (TPLO) or Tibial tuberosity advancement (TTA), dog owners can help keep their pets healthy and happy for years to come.
