When your little Shih Tzu is looking up at you with those big eyes, it can be difficult not to give in and give them a bite of whatever you are eating. Most of the time, this isn’t an issue as long as you don’t do it all of the time. However, there are human foods that can be toxic or even deadly for your pup.

18 Human Foods That Are Toxic or Deadly for Shih Tzus

There are a number of human foods that can cause your dog serious damage or even be fatal.

The following 18 should never be given to your Shih Tzu.

1. Onions and Garlic

Both onions and garlic can be toxic for your dog.

Not only can they cause gastrointestinal irritation, they can also damage red blood cells.

Anemia is another possible side effect.

It can take a few days for symptoms to show up.

When they do, they include:

  • Weakness
  • Lethargy
  • Orange to red colored urine

2. Avocado

Avocados contain Persin.

You’ll find this in the leaves, seeds, and the fruit itself.

And while avocado toast is all the rage, don’t share it with your Shih Tzu.

It can cause both diarrhea and vomiting.

Not to mention, the avocado seed is a choking hazard for you little dog and can cause an obstruction in their stomach or intestines which can be fatal.

3. Raisins and Grapes

Grapes are a wonderful treat anytime and frozen grapes are great in the summer, but don’t be tempted to give your Shih Tzu one no matter how much they may beg.

Both grapes and raisins can cause kidney failure in dogs.

Just a couple grapes can lead to severe vomiting.

Other signs include:

  • Diarrhea
  • Lethargy
  • Decreased appetite
  • Dehydration

While it is true that not all dogs are harmed by grapes, many are.

If your Shih Tzu has eaten some and show any of the above signs it is best to take them to the vet right away.

Otherwise you could be looking at long-term kidney disease or even death within three to four days.

4. Chocolate

Chocolate just makes life sweeter, but not for your dog.

Depending on the type of chocolate and the amount they are exposed to, you can see the following symptoms:

  • Diarrhea
  • Vomiting
  • Increase thirst
  • Muscle tremors
  • Irregular heartbeat
  • Seizures

Dark chocolate is more dangerous for your Shih Tzu than milk chocolate as dark chocolate contains more caffeine and theobromine which cause toxicosis in your dog.

You will want to keep your dog away from caffeine as well, so no sharing your morning cup of Joe.

5. Artificial Sweetener (Xylitol)

Chances are you use artificial sweetener in your morning coffee or tea.

If not, you still may come across it in sugar-free gum, the toothpaste you use, or even those chewable vitamins that are so much easier to get down than the regular large pills.

Regardless of where you find it, it can be deadly for your Shih Tzu.

Xylitol can cause a severe drop in your dog’s blood sugar levels.

It can drop so much as to be fatal.

Xylitol can also cause liver damage.

And it doesn’t take much.

For small dogs like Shih Tzus, one piece of sugar free gum digested by a ten pound dog can be toxic.

You should watch for the following signs that your dog has ingested a piece, or more…

  • Vomiting
  • Seizures
  • Loss of coordination

These symptoms can show up in a few minutes to a few hours.

If you think your dog has gotten a hold of a product with Xylitol do take them to your vet immediately.
