Here's why:
* Only a vet can properly diagnose the lump. There are numerous reasons for a lump on a dog's leg, including:
* Benign growths: These are non-cancerous and often harmless.
* Infections: A bite, scratch, or injury can lead to an infected lump.
* Cysts: These are fluid-filled sacs that can appear as lumps.
* Cancer: While possible, it's not always the case.
* A vet can determine the best course of action. This may include:
* Examination: A physical exam, blood tests, and possibly imaging (x-rays, ultrasound) to determine the nature of the lump.
* Treatment: Depending on the cause, treatment might involve antibiotics, surgery, or other therapies.
Please don't delay seeking professional veterinary care. Your dog's health is important.
