Hi - You most likely have demodex mange. Rocco has had it when he was just under 1 years old. You should search this website for a few previous posts I've done, and other's have also done in the past. They can be very helpful. My understanding is that bulldogs have weaken immune symptoms for the first 1 to 1.5 years of their life. All dogs carry the mites, but bulldogs seem to get more of the reaction. Rocco did the mitoban dips (not very common these days) - but I've heard the Ivermectin meds also do really well. It might take up to 4-6 weeks for him to fully recover, all hive/allergies to resolve completely and hair to start to grow back. The first spots typically start on the face, so it sounds like this is where it started with Gilbert. It is very good to be aggressive with the treatment. left untreated it can be very bad for your bully. After you get the mange/mites under control - look to change his food to help build his immune system. Lots of great suggestions on this site for how to change food (you do it very slowly over several weeks - not all at once!) and what foods are the best options. Also pro-biotics, and supplements/vitamins are all good ideas for boosting our bully immune systems. Rocco has been mite free for over a year - so I hope this is the one and only time you have to go through this too. Good luck, and feel free to let me know if you need any advice or support!
