3) A Bland diet.
When a dog's body is wiped out with the effects of upset stomach, you will want to offer very bland foods that are extremely easy on the digestive system. This allows both the stomach and intestines to have a rest while the dog still receives nutrition.
Do not use any seasoning other than a small dash of salt. A bit of sodium is needed to help replenish salts that are lost due to vomiting and/or diarrhea.
The best foods for an upset stomach are: sweet potatoes and white rice, whipped nicely into a mash that is easily chewed and swallowed. This is tolerated best when served warm. Give just a bit at a time, allowing the stomach to rest in-between bites. If you see that your Shih Tzu is doing well, you can add some white breast chicken meat without the skin.
During this time of offering relief to a queasy stomach, snacks can be plain white yogurt (regular, not non-fat. This is a good source of healthy pro-biotic bacteria that may benefit the digestive system.
Another good snack is plain, canned pumpkin - be sure to obtain actual pumpkin and not the pie mix. This helps to firm the stools. Do not give too much as it can cause constipation. A spoonful every couple of hours is best.
How long should you give your Shih Tzu a bland diet? Depending on how your Shih Tzu responds, this can be given for 1 to 3 days. If there is no improvement after 72 hours, this is your signal that it is time for the veterinarian to treat your puppy or dog for what is most likely an underlying condition.
If it is working, you will want to ease back into your dog's regular diet. This can be accomplished by continuing to feed the sweet potatoes, rice and chicken while blending in a bit of your dog's normal kibble or main food. A mixture of 75/25 can be given to start with, with gradual ratio changes over the course of 2 to 3 days.
4) Pepto Bismal -
Many owners wonder if you can give Pepto Bismal to a Shih Tzu. This actually is a safe over-the-counter home remedy for an upset stomach; however you will want to be careful in regard to dosing. It can help with nausea, heartburn, indigestion and diarrhea.
There are some genetic brands of Pepto that may have additional ingredients that make them unsafe for canine consumption; therefore it is best to stick with the original brand name. Pepto's active ingredient is bismuth subsalicylate, which coats the stomach and gastrointestinal tract. It also works to reduce internal swelling and can destroy some types of bacteria.
Please note that this is a temporary fix and it is not safe to keep giving a Shih Tzu Pepto for moderate to severe stomach problems. This would only be an attempt to cover the symptoms and not resolve the underlying problem.
The best way to deliver this to a Shih Tzu is with a safe plastic feeding syringe. You would aim for the inside side of the mouth; do not shoot it straight down the throat. Once it sits in the inside corner of the cheek, gently close your puppy or dog's mouth, and this will trigger him to swallow the medicine.
How much Pepto Bismal you give your Shih Tzu will depend on his weight, not his age. The proper dosing is 1 teaspoon (15 milliliters) per 5 pounds (2.26 kg) of body weight. Therefore, just a small amount is needed. You will want to give your Shih Tzu a dose every 2 hours. After 4 doses (8 hours) if his stomach has not calmed down at all, it will be time to contact the vet's office. Be sure to let them know that you offered this OTC medicine, as it can interfere with x-rays and other scanning tests if those are to be given.
The possible side effects include dark stools, a darkened tongue and/or constipation.
