Ian and I went to NYC for about 5 days, so Chili and Bridgett got to spend some time at my in-laws' house, and play with their 2 Boston Terriers! Both dogs behaved well, to our relief!
Chili didn't get to go on the normal walks my in-laws usually take him on (vet's orders). Poor little guy did get to spend some quality time outside in the yard though, which I think he enjoyed. Overall, I think both pups had a ton of fun and got totally spoiled, but like us, enjoyed coming home, too!
Being away from Chili for almost a week, I got to have a fresh look at how he's acting with his leg. Sadly, there was no incredible miracle, and he still has the luxating patellas (hey- I can hope, right?) He wasn't wimpering at all while we were gone, so he didn't need any pain pills, which is a good thing. He's still a little tender around the leg, though. He did whine a little when I touched it, and he frequently looks back at it and licks it. We have 8 more days until his surgery. He's sleeping well in a crate at night now (in preparation) and we cut down on his food, since he isn't getting any exercise, and I don't want him overweight before or after the surgery (I still worry about anesthesia complications, and I also don't want any extra weight on his joints that he doesn't need). He is, of course, completely clueless about what is going on, and is probably wondering why mommy and daddy yell at him whenever he tries to jump or climb stairs.
I'll post another update in about a week, just before the surgery. I'm also making an online gallery, so we have some pre and post surgery pictures available.

The Luxating Patella
We didn't have Chili long before we realized something was wrong. Whenever he would walk or run, he held up one of his back legs (usually his left). We couldn't find any source of pain, but we wanted answers! Dogs are supposed to walk on all 4 legs, not carry 1 in the air. We took him back to our vet.
*This is a photo of Chili running with his back leg held up*
The vet diagnosed Chili with something called a Luxating Patella, or a kneecap that slips out of joint. She said it wasn't causing him pain or discomfort, but referred us to a surgeon for a consultation.
The surgeon looked at Chili's legs and diagnosed him with a grade 2 luxation on the left and grade 1 luxation on the left. (The grades refer to how bad the luxating patella is, depending on how easily it slips out of joint, and how hard it is to get back in. Surgery grade is considered a 3.) Chili was just over a year old at the time, and the surgeon recommended waiting on surgery. He did warn us that Chili would most likely need it at some point in his life. We were satisfied with the answer, so Chili just hopped and skipped along like a happy little dog.
Here is some additional information I found online that was published by a veterinary hospital. To see the full article, please go to http://www.cpvh.com/Articles/78.html
LUXATING PATELLA (KNEE CAP)
Patellar luxation is a dislocation of the knee cap either toward the inside (medial) or outside (lateral) of the leg. The patella and its ligament normally rides in a trough or trochlear groove in the center of the leg (femur). It is one of the most common knee joint abnormalities in dogs.
Luxation may result from traumatic injury or congenital (present at birth) deformities. If the groove that the patellar ligament (knee cap) rides in is too shallow or if the distal attachment of the patellar ligament is medial instead of central, the patella will dislocate medially when the knee is bent. When this occurs, the dog (or cat) has difficulty bearing weight on the leg until the ligament snaps back into place. Sometimes only one knee is involved, but the disease can become bilateral (involving both legs) in 50% of cases.
Patellar luxation is most common in toy and miniature dog breeds, especially Poodles, Yorkshire Terriers, Pomeranians, Pekingese, Chihuahuas, Miniature Pinschers and Boston Terriers. It is uncommon in cats, but may be more common than suspected because most affected cats are not lame.
Clinical signs of patellar luxation vary depending upon severity and chronicity of the disease and may develop soon after birth or generally after four months of age. With mild forms of luxation, animals may occasionally pick up the affected leg when they run. As the disease progresses, animals may present with increased lameness with a decreased ability to jump. Pain is usually not associated with this condition unless it is the result of trauma or until degenerative arthritis has occurred due to chronicity of disease.
Some pets can tolerate this disease for many years, some for all of their lives, with minimal consequences. However, this weakness of the knee joint can predispose the knee and even the hip joint to other injuries such as degenerative arthritis and torn knee ligaments, both painful conditions.
Grade I -- The patella can be manually luxated but easily comes back into normal position. Patient may or may not occasionally carry the affected leg.
Grade II -- Patella luxates on flexion of the knee joint and remains out of place until manually replaced or patient extends and rotates joint. Patient intermittently carries the affected limb with the knee joint flexed.
Grade III -- Patella remains luxated most of the time but can be manually reduced (placed back into position). Flexion and extension of the knee joint reluxates the patella. Patient transfers most of the body weight to the front legs, bunny hops or carries the affected legs, and appears bowlegged or knock-kneed.
Grade IV -- Patella is permanently luxated and cannot be manually repositioned. The quadriceps muscle group starts to shorten, making it difficult to extend the leg fully. Patient transfers most of the body weight to the front legs, bunny hops or carries the affected legs, and appears bowlegged or knock-kneed.
Patellar luxation is diagnosed based upon history, physical exam findings, and radiographs.
