What is the cause of swollen legs in dogs

Swelling of the dog’s leg, which involves the dog’s bones being hit by an external force and the swelling being caused by a ruptured blood vessel, is a traumatic cause. Inflammatory infections can also cause a dog’s legs to swell. Venous embolism in the lower limbs can also cause swollen legs in dogs, as can hypoproteinemia, and then there are bites from some poisonous insects.
