Hello. I am sorry to hear that Bob is not doing well. Unexplained weight loss is always a concern and can be caused by many different factors including gastrointestinal diseases (worms, food allergies, IBD, absorption disorders), metabolic diseases (diabetes, liver disease, kidney disease), heart disease and airway disease. If he is getting dizzy this can be a sign of lack of either blood flow to the brain, or lack of oxygen to the brain. This can be the cause of either heart disease or lung disease. Dizziness can also be due to anemia which can be caused by kidney disease. Lethargy is a sign of all of these conditions. As you can see, Bob has very non-specific signs, but his condition sounds serious. I would strongly recommend that you see your veterinarian, and they will likely wish to pursue bloodwork and possibly an x-ray of the chest. I hope Bob gets better soon!
