hello! New here to this! I have an almost 4 yr old male bulldog named booger who has been the poster child to all bulldog issues from the time we got him to keep it in short. About beginning to mid April booger started to vomit bile in the am upon waking or in the middle of the night. At first we assumed it was grass as a few times he threw up there were a few blades of grass in the foamy bile. When he gets excited outside and doesn't have a toy insight he mouths at the grass to try to show you something. He has no intention on eating the grass and tries to spit it out after doing so but it's hard to have company over or play with the other two dogs when he does this upon excitement. Anyways he has a long history of multiple bouts of aspiration pneumonia. He has had 2 nose surgeries and the soft pallet surgery. We had about 1 good year with him but seems during a few times a year he would have a spout of vomit, usually receiving antibiotics because of aspiration and we would be ok another 6 months or so. This year we thought it was one of those episodes again however we have been careful and he has a specialist of internal medicine at avets he sees regularly because of all the issues and we dont want to wreck his immune system so we only give medicine it absolutely necessary. He was given a very small dose of an antibiotic because our vet thought he had a small respiratory infection and they wanted to get ahead of it before it maybe would branch out to be pneumonia again. From that point about a week later he was doing really good. About another week later we started vomiting again. He went to see his specialist and she ran blood work did x rays did ultrasound checked pooped urine sample the whole shabang because at this point we don't play around with the wait game when anything is wrong. We rolled out anything with his liver pancreas and all tests were normal except white blood cells were a little higher but not alarming. She decided we needed to change his food as he was on canned hills sensitive stomach and skin the salmon and veggie formula and took a daily probiotic fitoflora. (He eats 3 times a day) (immediately upon waking, around 2pm and at 830 or 8pm) (he is usually sleeping by 830 or 9pm, he also has a history that if he eats too late he will vomit with food in middle of the night so he needs an hr before bed to walk around and digest) We switch him to purina pro plan ha hydrolyzed formula chicken dry food. She said this food will help his body only recognize this food as amino acids incase he developed a sensitivity to the food he was currently on all of a sudden. Side note he also has been to a dermatologist to role out allergies since my other bulldog has severe allergies. We are on week 4 of fully only on this food and it took him about 3 weeks to fully transition as he has a history of not doing well switching foods. I have kept a daily log of when he vomits this bile and how much and specific times. The longest gap has been about 9 days but is usually about every 4 to 7 days where we see a morning vomit. He does nothing different in his day to day life as I also track that, his water intake and if his belly is rumbly or gassy. I have the opportunity to be home with him 24/7 and he is never alone. He does have a bad habit of licking his paws as he can't have bones or chews or most toys because he sucks on them rather than chew them and will get mucusy and stuff from doing so. I do catch him within seconds of doing this and he then quits. We have another follow up with the specialist this Tuesday but am worried with what additional tests she will want to do as we dont want to put him under unless 200% necessary. He has also been rolled out for rare diseases such as mega esophagus and they have done scopes to make sure he didn't have a hole anything as well. I guess I'm posting to help educate other bulldog parents and I have many more stories to share and information regarding all things bulldog and I also am wondering if anyone has experienced something similar with their bulldog? I know there's a lot of rambling details but like I said we don't know what connects to what and he's had a rough history of chronic issues. Any advice or suggestion would help us through this next phase with him and I plan on updating as this continues.
