Hair loss is usually due to excessive itching, from allergies or fleas. If this is the case, I would recommend a visit with the vet to get London started on an allergy medication and a good flea control. If you have not noticed any itching then the hair loss could be from an endocrine problem (the body system dealing with hormones). The two main diseases that can cause hair loss are hypothyroidism and Cushing's disease. If you or your vet are concerned this may be the issue some blood work can be performed to rule these diseases out. I hope this helps. Good luck.
