Had both of my kids out today guiding at a shooting preserve. All went well after we finished there were no apparent problems, loaded dogs had a beer in the clubhouse and went home after about an hour and 1/2 we arrived home . Unloaded didn't notice anything but shortly after my young dog (45lb pistol of a bitch) is not putting any weight on a rear leg. I'm hoping a strained muscle witch after cooling off is now stiff and sore. What I'm asking is would a tear show up right-away? Gave her an asprin and confined her and will see what is what in the morning.
