About yesterday morning, my 7-month old pup started limping. It was very unexpected and I really can't predict what caused it other than the fact that he was very hyper and running around the place in the morning (as usual the second we let him out of the crate).

Anyway, his condition yesterday was:
-did not do much walking, just layed in bed all day
-appetite seemed normal

Today's condition:
-appetite seemed quite normal
-tries to play with me but can't due to limping
-walks around the house more often
-still limping --> condition doesn't seem to have changed

I'm quite worried about my dog and have done some research about luxating patella but it seems like he is too young to have this. I am not sure if I should take him to the vet and if I do, I would like to know what I should expect.

I'm also concerned about costs. It seems that any conditions involving weak knees will most likely lead to costly medical treatments. Does anyone have any tips/recommendations on how I should approach this? I am looking through pet insurance plans but they are so confusing and pricey.

Thanks again for your help
