I have a 6 y.o. Border Collie/Aussie mix, Daisy. Lately she has been having trouble getting up when she lays down. When she does lay down, she only lays on her side with her back legs strategically placed. She still runs, just not for long distances. Sometimes she limps. The pain seems to be contained mostly in her right rear leg. I have been doing a lot of research on Hip Dysplasia and Arthritis. I am really hoping that this can be easily treated. I was looking for some more input on this. Thanks!!!
