My Australian Shepherd (who happens to be a lethal white variant) developed this hard trilobal growth around her shoulders. It is white with black speckles. It doesn't seem to bothe her and it it hasn't grown since I found it. I have seen these on other dogs but usually their head and they bleed, Anybody ever seen one of these

I am a little puzzled by your description 'trilobal'; probably should be triloble meaning 3 part. I have never seen this on a dog. Where did you come by this description? And can you provide a picture?

I will try to get a pic for you, but then comes the problem of me trying to get it onto the computer. Please excuse the spelling I am a respiratory therapist so I think in lung lobes LOL
Yes it has three distinct areas,I thought maybe the lump described as cauliflower looking might be it but the rest of the description doesn't fit.
Thanks
