A dog's particularly bloated and hard belly may be caused by indigestion, internal parasites, abdominal bloating, abdominal tumors, etc. If your dog’s belly continues to be swollen and hard, it is best to take your dog to the pet hospital for examination to confirm the cause and treat it promptly to avoid delaying the condition.

Tips:

Do not feed your dog hard and difficult-to-digest food. Feed probiotics regularly to promote gastrointestinal motility.
