We have rescued upwards of 500 Bulldogs over the past 10 years and most all of them (99%)are rehomed with great skin and we feed Now Senior food. One boy we have right now did not do well with it so we are feeding him Merrick Salmon Ltd Ing. Those two foods are our Go To brands. There are many others that will give similar results and Fromm is one. Many owners here feed it...just find the right mix. Lower protein is recommended for an older Bully.
