I have mentioned before a clicking/popping noise my lil corgi, Mousse, makes while walking. I thought it was her nails, but they were just clipped. Now however, she has started to limp. Also noticed a change in behavior, almost like she is depressed. (she goes to bed early, lies around more, etc.) I'm concerned it might be a combo of issues including joint issues, but not sure. I am thinking she is probably going to have x-rays done if I take her to the vet, and was wondering if any of yall have heard of anything similar, how much x-rays/bloodwork usually run, if it would be more cost effective if I started pet insurance, and which pet insurance would be the best if I did. Thanks again!
