Rodney had a large mass removed from his left hind leg yesterday. The Dr thinks it was a benign neoplasm but we're sending it out to find out for sure. He gave him 10 stitiches that need to be removed since it was so large.
Same masses grow really, really fast. Unfortunately, when that happens, it's almost always bad news. Not always, though. Hopefully, you caught it early and the margins will be clear.
My dog had a Trichoblastoma grow to the size of a nickel and about an inch high over the course of just a few days. It scared the crap out of me. Thankfully, the margins weer clear and the prognosis is excellent.
