I dropped Spike off early this morning for his surgery. True to form, he has licked and chewed on his bump until it is raw and bleeding. I am glad that it will be removed today. Although the thumb size bump is classified as a wart there is always a chance it may be cancer. I am a little worried since it tripled in size in a matter of weeks. My dear old Spike, you're just an old mixed breed mutt, but I do love you so....Keep your paws crossed.
