My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
It always worries me to hear about a dog with a distended stomach as this could indicate bloat. Bloat (Gastric Dilatation) may or may not involve stomach torsion (twisted stomach). Common symptoms are attempts to vomit (usually unsuccessful) and may continue to try to vomit, dog just doesn't seem like themselves, a hunched up posture, anxiety and restlessness, a distended stomach that is tight like a drum, gums may be dark red in early stages and white or blue in later stages. These are the most common symptoms and the list goes on.
If you believe your dog has bloat they should be seen immediately even if you have to take them to an alternative vet. Simethicone products like gas-x may help while you take Hank into the vet.
You can find another vet using this site. I'd use the emergency visit search.
You can read more on bloat here.
If your dog eliminated today then constipation should not be causing a distended stomach. However, severe constipation can lead to a bloated stomach. Parasites can sometimes cause a distended stomach and lead to a loss of appetite as well though we usually see abnormal stools with parasites.
If your dog may have ingested a bone or sharp pointed object, it may have punctured the gastrointestinal tract. That would also be an emergency. You can read about this here:
Cushing disease can cause a bloated stomach as well. You can read about this condition here:
Only you can see exactly how sick your dog is and make the determination on whether an ER visit is necessary, but I can give you the possible causes to help you make the decision. I'd give gas-x (Simethicone) now just in case. The following lists the dosage information for Gas-x as 1 adult dose for large dogs. If bloat suspected, then 2 doses should be administered.
