This morning my Dog (8 years old) woke up with 2 swollen front legs and is limping. What can I Do?

Take the poor thing down the vets for a professional to look at IF it doesn't seem to clear up itself after a day, it may be a reaction to something or he just slept in an odd position or something else. Without having a look myself it's difficult to judge so my standby advice is go seek a pro's advice. With any medical issue people or animals it's never really a good idea to seek answers on a forum board :( hope the doggy gets better soon.
