When grooming Heidi today i noticed a pea sized lump on her shoulder . It appears to be a tiny syst . I'm scared stiff, Ruby got one on her tummy and it enlarged . When she went to have it removed at the vet's she died of a massive heart attack when they gave her the pre med. Is this going to happen again . Any advice from someone who has had something similar or am I being paranoid.
