Our male dog is about 9.5 years old. He weighs in at about 65 lbs and is about the size of a border collie. He is still very active, barking and running; he's generally just goofy. We've recently discovered that he's developed a bubble of fluid under/near his front leg along his rib cage. Could this be serious? It doesn't seem to bother him. We're making an appointment for him but wanted to know if it is urgent. Thanks.
It does not sound urgent but I would have it checked out by the vet. Vetcare
