I recently noticed a tumor like growth on my Danny's one of the thighs ( right). And black dots like marks all over the body. He is not much active since 3 days. Anyone knows what is this ?

Hi Aishwarya. The growth can be a tumor of any origin/abscess/hematoma, which should be confirmed from a test called fine needle aspiration cytology. The black spots occur due to yeast or fungal infection or hyperpigmentation of the skin. It’s best to get get your pet clinically examined thoroughly for the better diagnosis and treatment.
