As my girl gets older she is getting more and more smallish black rubbery textured tick like growths. She has one large one which I brought to the attention of my vet last year. She told me she had more serious health issues (like the sever muscle wastage/& DM symptoms she has ) and I should not worry about them - but I do. Anyone else have these on their dogues ? I remember that one internet search I did seemed to indicate a cancer type growth but have never seen anyone else complain about anything similar.
