Hello, My name is XXXXX XXXXX I have been a veterinary nurse for 26 years.Thank you for allowing me to assist you today.
I am sorry to hear that you are concerned with bloat but very happy that you not only know about this possibility but are taking the time to try to educate yourself on what precautions you can take.This is not common in all large breed dogs more so large breed dogs that are deep chested such as the Doberman and Great Danes.
While there are no medications that can be taken to prevent this there are things that can help reduce the risks.
1. Always wait at least one hour after eating and drinking before allowing the dog to do any exercise such as running jumping etc ( a simple slow walk is fine)
2. Do not encourage or teach deep chested dogs to roll over. While not a high risk some experts believe that a full roll over can increase the risk of the stomach twisting
3. Feed smaller meals throughout the day. Some owners feed 1-2 times per day but splitting the meals into 3-4 meals per day reduces the risks of bloat.
4. Do not allow the dogs to drink large amounts of water right after eating.
5. NEVER elevate the food bowls. Some owners of larger breed dogs use the elevated dishes thinking it makes the dog more comfortable when eating. This is proved through research to greatly increase the chances of bloat.
6. Some experts recommend not feeding dry food only to either mix with wet or moisten the food with water or broth.
It is also a good idea to always keep Gas X on hand if you have a breed prone to bloat.
Here is some additional information that might be helpful as not only do you want to know potential ways of avoiding bloat but also how to recognize the early signs. LINK
I hope this helps. Please reply back if you have additional questions or concerns and I will be happy to continue.
