I'm so sorry to hear about your puppy. My Riley also has hip dysplacia in both hips and we found out at 10 months of age as well.

Second opinions never hurt, and there's different ideas around treatment.

There's three major surgical corrections to hip dysplacia at this time.

1. Triple Pelvic Osteotomy (TPO) is usually performed on dogs 10 months of age and less and only as long as the joints do not show sever damage or have become solid/developed and damaged. It's basically a hip re-alignment where the pelvic is broken and reshaped to the joint. The dogs wieght also plays a part in this. This is most common if caught early in puppyhood and is quite expensive.In the case of Riley, her joints were already too well formed to perform this surgery and it was determined that she was too old, at 11 months.

2. Total hip replacement. Just like it sounds, very expensive, and usually takes about 3-4 months to recover. This is the best bet for adult dogs, but is sometimes the best course if the hip(s) are too badly worn. Typically performed on young adult dogs as the bones have to be fully matured.

3. Femoral Head and Neck Excision. This is a salvage at best and includes the removal of the femoral head. In place the body produces a fiber like substance that pads the joint. This is typcally reserved for older dogs to reduce/remove pain from bad joints. The dog's weight is a major issue and again this is almost always for older dogs.

There are other surgical treatments out there, but I don't know them too well and are not as common.

There are medications that can enhance the quality of living for a dog with hip dysplacia and this is where a second even third opinion is always valuable. Often these are in the form of steroids, pain relievers, and anti-inflamitory medications.

Low impact exercise such as swimming is great for dogs with dysplacia. This is because weight is a major issue. It's a catch 22. It's hard to exercise a dog with dysplacia, but being overwieght amplifies the affects and harms the joints even more. Low impact, and controlled exercise/play time is a must.

In my case Riley gets many short walks and lots of of play in a small area. She gains weight easily so she's on a reduced calorie/fat diet and I do the best I can. She knows her limit for the most part, and I can see when she is sore and we stop. If for whatever reason she seems uncomfortable then I give her, her medicine and we have a slower day the next morning.
