I am hoping that I would be able to get some onfo. My 3 1/2 yr rottie has develped lumps. one the sz of a walnut on her leg. others smer than a pea, now I have dicovered them around her anal area very sm. All are fleshy and shrink but they worry me and would like to know before I let the vet preform surgery on her. Any info would be very helpful. Thank-you she means the world to me
