I have a nice hard runing lil gyp that after I run her holds he back leg up and acts like it bothers her! The thing that confuses me is there is nothing wrong with her pads, toes ,toenails or joint above the lower leg! I say that cause I rubbed, pulled, tugged and poked all and she doesn't even make a wimper ! Raised leg ,felt hip joint it doesn't but or have ahitch !! Like said she doesn't wimped a bit!! Even massaged muscle in thigh and hip still nothing but she will hold it up(leg)!! Any thoughts cause in my 25 years I haven't seen this before! When you turn her loose it doesn't bother her at first I do notice later on she not as strong but i haven't notice her holding or favoring it! But it's gotta be bothering her. What are some of the things y'all think I can do?? Thanks for any help God bless and happy hunting /running!!
