Tonya is right. I see growths like that ALL the time on older dogs at work, they are extremely common on cockers. The ones I am referring to are pinkish in color and they do bleed sometimes. RB Smokey (poodle) and RB Reggie (schnauzer) had them too. Smokey had a ton of them, the vet cut them off and they just grew right back. I would recommend she have a vet take a look at them to confirm they are the "warts" and not some other growth.
