So as an owner of a limping dog, I ALWAYS get people offering advice. Yesterday morning I just lost it. After my normal explanation of 'he's an old dog with a bad leg' didn't work, then I had to go into the cancer radiation neuropathy which didn't work either (he didn't know what neuropathy was, should have just walked away at that). This guy just HAD to tell me a dozen times about this fabulous supplement for old dogs that transformed some neighbors 3 dogs. Now Gavin is in amazing shape besides his leg, and this guy was just annoying me and he knew it. I just couldn't bring myself to tell him to STFU and leave me alone, or tell him supplements aren't clinically tested and unless there is a specific deficiency or issue you are addressing they are worthless. Cause how could a middle aged white woman possibly know anything better than a guy with a 3 year old pit bull? But it begs the question, does 15 qualify as an old dog?
