Snickers my GSP is 4 and for almost as long as I can remember when we take him on walks he will always, at least once, drag his rear paw. I hear the nails scrape, and then I'll watch him walk for a while and then it almost seems like his right hip drops ever so slightly and the paw will drag as he moves it forward. I was wondering if this is a symptom of some genetic condition I should be worried about or am I just being overly concerned? Maybe he's just dragging his foot because "it happens"...or maybe his toenails are a little too long that day...
Food for thought.
Something is wrong I'd say, I'd have him checked for sure. Good luck.
In most cases this is neurological in origin. Something is interfering with the travel of signals from the brain to the rear. There are multiple causes. Investigate now to get a better understanding of what is happening and how to address it.
