Luxating patellas are more common in smaller and tiny dogs. This means the knee cap floats in and out of the joint. It is assigned certain grades based on the severity. I believe it is out of 4. So a 3/4 is pretty severe.
However, there are some things to help the condition before surgery.
- Maintain a healthy body weight to limit stress on the joints
- Light exercise regularly to keep your pet moving. Toned muscles help anchor the knee cap better than loose ones.
- Glycosaminoglycans might help, but talk to your vet before administering.
- Discourage large jumps up or down. Provide your pet with size appropriate stairs if he wants up on the bed/couch etc.
- Focus on proper diet. Low carbs can help reduce inflammation around the joints.
Keep an open dialogue with your vet about the condition. Patellar Luxation is not something that dogs just grow out of. There isn't a medication that can make this better. But, usually patellar surgery is less expensive and less invasive than other types. However I would probably wait until your pup is done growing, and have a vet look at the knees again. Growing puppies are often misdiagnosed, but if the diagnosis remains the same as a mature adult you will need to consider your options.
But, it's really on a per pet basis. As stated earlier, I would look into pet insurance. Though most of them have a preexisting condition clause; this condition is now preexisting; however, they might help with expenses. Otherwise, discuss with your vet about a payment plan or perhaps utilize Care Credit if necessary. Surgery is always a last resort and if your vet is urging you forward at this stage, it never hurts to get a second opinion.
Good luck!
