Hello all, new to the forums here so forgive me if this is in the wrong subforum or has been asked numerous times. I recently acquired a friends english bulldog who is almost 5 years old. As a puppy she had her back right leg operated on to fix her patella issue and has been fine since. A few days ago she chased a rabbit around the backyard (didnt see it in there or else i would have gotten it out prior to letting her outside) and i think with all the running around messed up her other patella. She wasnt putting any weight on it for a couple days so I took her to vet just to make sure everything was ok. Long story short the vet said her patella was popped out hence why she wasnt putting any pressure on it. Once she put it back in place the dog immediately put pressure back on the leg but within a few minutes she was favoring it again as it slipped back out. Should this be something I should be really concerned about? I've tried doing research on it last night and I see there are different "grades" levels of this but wasnt sure how sever this is. I've had her for about 3 months now and she never showed any signs of it being a problem. She always runs around the house to play and runs up and down the steps in the house. Even when it was out, I was touching her leg and moving it and it didnt seem to bother her as she didnt yelp or try to pull it away. Any feedback would be appreciated, sorry for the long post
