My Great Dane is sick every night with gas. What can I try next?

Updated On September 23rd, 2025

Pet's info: Dog | Great Dane | Female | spayed | 9 years and 6 months old | 0 lbs

I have a great Dane 8 years old and for the past months she has been being sick most nights always at night. She has been to the vets several times ,, they have scanned her stomach but can only find a build up of gas , they also found a heart minor. She takes anti sick medication twice per day and medication for her heart . Medication for sickness does not seem to help. She eats a dry sensitive stomach feed. She is a normal dog during the day eats drinks well plays etc . Any ideas would help.

I am so sorry to hear that your pet is so ill. Build up of gas in the stomach is often times caused by either bacteria sitting in the gut (if the intestines are not distended), or due to a foreign body obstruction or partial obstruction (if the intesitnes are also distended). If she has an underling heart condition, this further complicates things. In order to best help you we will need to go over the details of Elsie's condition to get all the necessary information and details of her treatment. This is a very complicated matter and we want you to get all the information needed to make an educated decision moving forward with Elsie. Also I am not sure what symptoms she currently has because you only mentioned that she is "sick". This can mean a lot of different things and should be clarified before recommending any additional treatments for her. I hope that your pet Elsie is able to stabilize her condition soon and we really hope to hear back from you for a one-on-one session. Take care!

    Hello. I assume the anti-sick medication you may be giving is either famotidine or omeprazole. Elsie may need something a bit stronger like sucralfate. You might also consider trying a diet trial with a more directed diet such as one for allergies. I have had many dogs do much better when switched to Hill's Prescription Diet z/d. I also put these dogs on an omega-3 fatty acid supplement, generally giving 20-30 mg/kg 1-2 times daily & adding a good probiotic to Elsie's regimen. Fortiflora is a very good one & available OTC. Thanks for using Petco Pet Education Center, formerly Petcoach.
