Hi and welcome! I'm new to the world of bulldogs as well. And it is a learning curve for sure! The lemon juice is for if they overheat and start "roaring" and can't breathe. A 50/50 mix with water in the side of their mouth with clear foam and help the airways clear so they can breathe. So it's good to just have some on hand in case of emergency. I don't know much about the whole puppy stage since I adopted a 3 year old and all that was behind him. What I can tell you is educate yourself on ALLERGIES. Bulldogs are really sensitive.A.LOT. Grain free diet seems to be the best all around way to go. Fromm Beef Frittata and Fromm Pork and Peas seem to work REALLY well. Petflow.com is a website where you can set up auto delivery. And there's a EBN coupon code you can enter in. Also get in a routine for wrinkle care, ear care, tail care, nail care, etc etc and so on. Kong chew toys, nylabones, and antlers are a good choice for chewers. There's a TON of fantastic bullies, owners, advice, articles, videos etc here. This forum has been a LIFESAVER!
