Sarge and Lola, First, Welcome to EBN and Sarge thank you for your service. Lola is a pretty girl. You will find much information here at this website. As fars as what is causing Lola issues...The main thing is to try to figure out what the allergen is causing the problem and try to eliminate it. If you are feeding the same food, that should not be an issue. I feed Jewel and Bentley Royal Canin Bulldog and also give them a daily supplement NuVet plus which we just started. I have not had any problems so far. Other members will most definitely chime in here.
