Can you tell me what causes this, my dog had bad gas for over 1 month. We came home one day and he looked sick-we took him to the vet but they weren't able to save him. Was there something we could had done that caused this? We also were concerned that someone may have been feeding him something during the day.
It sounds like your pet has a condition known as "bloat". The true cause is not known yet. It is commonly seen in deep chested dogs. Many dogs do not survive this. Do not feel bad, it is not your fault. vetcare
