I'm by no means a certified Vet but I've been researching this board as well as some other sites on "pano". Not sure if my boy is suffering from it. He is 16 months and has ben limping on his left fore leg since Saturday. When Pogi sits he leans more on his right front leg and lifts his front left paw. Interesting thing is that when walking he favors his left side but when has the chance to Run...He takes off!! and it doesn't seem to bother him...any ideas??? I've read that it is painful but he hasn't yelped in pain and continues to be his active self but still favoring he left leg...I have a Vet appt this coming Sunday...hoping that a week will allow the issue to possibly go away.....Any Thoughts???
