Antibiotics can cause an upset stomach and nausea to make him feel bad. You may need to change foods to a sensitive stomach or prescription diet formula such as Science diet I/D or W/D to help with going to the bathroom. You can also add miralax to the diet, 1/8 teaspoon twice a week. The best things for hair loss is the continue brushing it to get the clumps out. This can be a sign of stress or an infection. Depending on what type of antibiotic you are on, this may treat that skin also. You can add omega 3 fatty acids to the diet to help with the skin and shedding also.
