My small dog has a torn ligament but isn't in pain. Is that normal?

It is difficult to assess without a full history of the type and severity of the injury. The most common type of injury is to the cruciate ligament inside the knee - although this can stabilise quite well with rest, weight management and joint supplements (especially in smaller dogs under 10-15kg), surgery is the recommended route in order to minimise the severity of arthritis which will develop due to the joints being unstable. Some arthritis is inevitable but it should be less severe and develop later in life if the joint is quickly stabilised with surgery

Limping can mean a lot of different things, including a muscle sprain or a ligament injury. It also depends on which leg is affected and exactly where the injury is on the limb. It is best to get your pet evaluated by a vet who can do a lameness exam to localize where the problem is on the leg. They will be able to recommend the appropriate treatment, whether it is just anti-inflammatory medication or potential surgery if the injury is involving the ligament. Many dogs will appear to act completely normal with a knee ligament injury.

Arthritis is very likely, sometimes it is exacerbated by another injury. It could also be a ligament sprain or muscle strain. There is also the less likely possibility of a hairline fracture or something more sinister like a bone tumour.

Poor Lily. When a pet isn't showing a pain response but limping on their back leg, it could indicate that they have either torn a ligament in the joint or have a severe muscle sprain. Also if you don't notice any obvious swelling, then a fracture is likely not the cause. Rest her, no running, jumping playing and leash walk only for the next couple of weeks. You can also do cold compresses on the limb 1-2 times a day. if there is no improvement within 3-4 days, then it's best to get her seen by your veterinarian for a full exam and pet friendly pain medication. She may also need x-rays of the leg to determine the underlying injury (cause). Do not give her people pain meds however because these can be quite toxic to pets and cause major liver and/or kidney damage. It's better to get all pain and anti-inflammatory meds from your vet. Even though she isn't crying out, there is presumed inflammation at the very least, so she can benefit from medication at any time. I hope your puppy gets well soon. Best wishes.

If her pain is truly localized to the hip it could be from a joint injury or arthritis. It’s also possible that the pain is originating from the knee - unfortunately many dogs that experience a cruciate rupture will have the other leg rupture within 6-12 months. If the lameness continues I’d recommend having Dallas examined by your vet.

Poor Lily! There are many different possibilities in this case. It may be that she has simply bruised herself or damaged a muscle or ligament. However she may have a more serious injury such as a fracture or ligament rupture. If she seems to be comfortable and nothing looks out of place you could let her rest 24 hours then if she is no better or getting worse head to the vet.

Since Sami can't talk, only a physical exam will be able to determine the source of the lameness. Just like people, the pain/limping can be related to many causes including a ligament tears, soft tissue injury, a developmental abnormality or even a spinal issue. You may try strict rest for a few days (no walks, running, jumping or stairs). If Sami does not improve or if he gets worse, have him examined by the veterinarian. Pets who exhibit toe touching lameness on the hing legs are a concern for a tear of the cranial cruciate ligament which is serious. He may need radiographs and the doctor will determine this based on the exam. I hope he starts feeling better quickly.
