Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! Bacterial or sometimes fungal infections of the skin can cause the hair to come out in clumps along with a scab. Certain endocrine disorders like hypothyroidism and autoimmune diseases can cause similar symptoms as well. It is hard to say exactly what the bump on the neck may be. This could be sebaceous cyst, an abscess, or small mass. It would be a good idea for TImberlynn to have an exam and evaluation done with her veterinarian. Your veterinarian may take a small sample of the mass to determine if it is concerning and needs to be removed. Your veterinarian may recommend antibiotics and/or blood work be done to rule out endocrine diseases as a cause as well. I hope this helps and thanks again for posting!
