Whats wrong with my dog he has tiny pea size lumps all over him more and more over the past three months hes only a 3 yr old Boston terrier?

It's important to consult a veterinarian as soon as possible, as the tiny lumps could be a sign of various issues, such as Allergies, infections, or tumors. Rapidly increasing lumps can indicate a more serious condition that requires medical attention. Your vet will be able to perform a thorough examination and determine the appropriate diagnosis and treatment. In the meantime, monitor your dog for any changes in behavior, appetite, or other symptoms.
