Dog with a Swollen Leg 

My dog had a similar situation recently, with his leg swelling 3x it's normal size. Turns out there were 2 boils around his "elbow" area on his front left leg. They had to be lanced, gushing infected pus, causing the leg to shrink back to normal size. He had to have painkillers and antibiotics to be back to normal.

My pugs back foot is swollen and he is not able to walk what should I do

What about getting a swollen leg after porcupine quills removed?

My dog is a great dane his legs are also swollen what should we do
