Our whippet had been diagnosed with this while he lived in Nashville with someone else. He had the growth removed twice (margins not clean). He didn't receive any othe treatment. He gets regular hemangiomas on the inside of his legs now that I just watch, according to my vet's instructions. He is white and spent way too much time outside in his youth. His diagnosis has been over a year ago and nothing has returned that I can tell. I didn't see them the first time, so I don't even know what it looked like. He does raw feed now, though.
