Can Dogs Eat Egg Custard?

Egg custard isn’t poison for dogs, but it isn’t a good treat either. It’s made from milk, eggs, and sugar. Milk can upset a dog’s stomach, and eggs must be cooked. A tiny lick of plain, fully cooked custard is unlikely to hurt a healthy dog, but it’s better to skip it.

Why isn’t custard a good treat for dogs?

Custard has three main parts, and each one comes with a catch.

• Milk. The ASPCA says pets don’t have much lactase, the enzyme that breaks down milk sugar. So dairy can cause diarrhea or other stomach upset.
• Eggs. Cooked eggs are a different story from raw ones. The ASPCA says raw eggs can carry germs like Salmonella and E. coli. If you can’t tell whether the custard was fully cooked, don’t share it.
• Sugar. The pages we read don’t talk about plain sugar in custard. Sugar adds calories your dog doesn’t need. A sweet, creamy dessert also isn’t a regular dog food.

We didn’t find a vet source that rates custard by name. This advice comes from what those sources say about each ingredient.

What can make custard dangerous?

Plain custard is mostly a stomach-upset risk. Two extras can make it worse.

• Xylitol. It’s more likely in “sugar-free” or “diet” desserts. Read the label before you share anything.
• Nutmeg. Many custards are dusted with it. Pet Poison Helpline says the small amount used in baking is very unlikely to cause serious harm, though a mild stomach upset is possible. A very large amount can cause serious signs such as confusion, a fast heartbeat, and seizures, and those can last up to 48 hours. That would take far more than a taste of dessert. Still, don’t leave a spice jar where your dog can reach it.

Can dogs eat egg custard tarts?

Better not. A custard tart has everything in custard, plus a buttery pastry shell. The Merck Veterinary Manual says eating trash, large amounts of table scraps, or other food that isn’t meant for dogs is believed to be a common risk for pancreatitis. That’s a painful swelling of the pancreas, an organ near the stomach. A whole tart is a lot of rich food for a dog. If a dog steals one, watch for the signs listed below.

Can dogs eat custard ice cream or frozen custard?

It’s the same issue, with more milk and sugar. Frozen custard is made with eggs and dairy too. Check the label for xylitol or other ingredients you don’t know. For more, see our guide on whether dogs can eat ice cream.

Can dogs eat vanilla custard?

Plain vanilla custard has the same problems as any other custard. Check the label of a store-bought one. Some are sugar-free, so look for xylitol on the ingredient list.

What if my dog ate custard?

If your dog licked a spoon or ate a small bite of plain custard, watch them over the next day. Mild stomach upset is the most likely result.

Call your vet if your dog:

• Throws up again and again, or has diarrhea that doesn’t stop
• Seems weak, very tired, or in pain
• Has a swollen or sore belly
• Stops eating
• Ate a lot, ate a whole tart, or ate something with xylitol

The Merck Veterinary Manual says pancreatitis can cause loss of appetite, vomiting, weakness, belly pain, dehydration, and diarrhea. Mild cases may show only a tired dog with less appetite. Tell your vet what your dog ate and how much.

What can I give my dog instead?

Pick something made for dogs, or a bit of your dog’s own food as a reward. Treats should be only a small part of the day’s food. A common guide is no more than about 10% of daily calories.

If you want to share something made with eggs, plain cooked eggs are a better choice than a sweet dessert. Read our guide on whether dogs can eat eggs. To see what’s truly dangerous, check our list of foods that are toxic to dogs.
