Skin lesions may turn out to be a harmless hemangioma, or a deadly hemangiosarcoma. A trip to the vet and a biopsy are needed to determine the best course of further action.
The cause of hemangiomas is idiopathic (unknown). These growths usually dont appear until at least middle age. Thin-skinned, light-colored breeds often experience hemangiomas. Youll most likely find a hemangioma on the dogs trunk or legs, especially hairless areas like the lower abdomen.
