Yes, plain, unsweetened yogurt is safe for most dogs, in small amounts. A spoonful of plain yogurt with live cultures, ideally Greek-style, makes a fine occasional treat. The two rules that decide everything are simple: it must be plain, and the portion must be small. Flavored yogurt, sweetened yogurt and any yogurt with xylitol are never for dogs.
Yogurt is one of the few human foods that brings something useful to a dog's bowl. The AKC notes that yogurt is high in calcium and protein, and that it can act as a probiotic, which can be good for the digestive system. The live cultures in yogurt are the reason: they are the friendly bacteria that help keep the gut working the way it should, and a spoonful of plain yogurt is a gentle way to offer them. That is why yogurt shows up so often as a recommended treat, and why it works well as a vehicle for hiding a pill or filling a chew toy. What yogurt is not, though, is a health food your dog needs. The AKC is clear that while a dog can get a probiotic benefit from yogurt, there are better sources of probiotics for dogs, so there is no reason to push yogurt on a dog that does not enjoy it or does not tolerate it. Think of it as a pleasant extra, not a supplement and not a staple. A healthy dog on a complete and balanced diet gets everything it needs from its main food, and yogurt is simply a small, tasty addition on top.
Yogurt is not toxic to dogs, but it is not always a good idea, and the reason is lactose. The AKC explains that dogs' bodies are not designed to digest lactose after puppyhood, so a food high in lactose can cause gas, diarrhea or vomiting. Puppies produce the enzyme lactase to digest their mother's milk, and most dogs produce much less of it as adults, which leaves many adult dogs partly lactose intolerant. That does not mean every dog will react: some dogs eat a spoonful of yogurt with no trouble at all, while others get loose stools from the same amount. The honest answer is that you cannot know which group your dog falls into until you try, which is why the first serving should always be small and why you should watch your dog for a day afterwards. If your dog gets gas, soft stools or vomiting after yogurt, the answer is to stop offering it, not to try a different brand and hope. There is a second reason yogurt is easier on dogs than milk. The fermentation that turns milk into yogurt breaks down much of the lactose, so yogurt usually causes fewer problems than a bowl of milk. Greek-style yogurt goes one step further: straining removes much of the whey, and with it more lactose, which is why the AKC calls plain Greek-style yogurt typically better for dogs. Even so, a dog that is truly lactose intolerant may not tolerate any dairy, and for that dog the answer is simply to skip yogurt altogether.
The tub you pick matters more than anything else on this page. The AKC's rule is plain and free of any added sweeteners, and the best choice is a plain yogurt with lots of live cultures, such as plain Greek-style yogurt. Read the label before you buy, and look for an ingredient list that is short: milk and live cultures, and little else. A plain, unsweetened, full-fat or low-fat yogurt both work; if your dog is overweight or prone to pancreatitis, ask your veterinarian whether a low-fat version is the safer pick, because fat is the other risk in dairy. Avoid anything labeled light, diet, low sugar or sugar free, because those are the versions most likely to contain artificial sweeteners. Check the label every time you buy, because a brand can change its recipe without changing its packaging. If the ingredient list includes anything beyond milk and live cultures, put the tub back. Plain is not a flavor. It is the whole point.
Most of the yogurt on a supermarket shelf is not for dogs, and the difference is what has been added to it. The single most dangerous addition is xylitol, also listed as birch sugar or wood sugar. The AKC warns that some artificial sweeteners, such as xylitol, are toxic to dogs, and the ASPCA names xylitol among the foods pets should never eat. Even a small amount can cause a rapid drop in blood sugar and liver damage, so a yogurt sweetened with xylitol is an emergency, not a treat. If your dog eats any yogurt with xylitol, contact your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away, and do not wait for symptoms. Added sugar is less dangerous but still not for dogs: it adds empty calories, feeds dental problems, and has no place in a dog's diet. Chocolate flavored yogurt is never for dogs, because chocolate is toxic in any form, and our chocolate guide explains why. Fruit yogurts can hide raisins or grapes, which are toxic, and our grapes and raisins guide covers that risk. Yogurt with macadamia nuts is also out, and our macadamia nuts guide explains why. The rule is simple: if it is not plain, it is not for your dog.
A spoonful is plenty. A teaspoon is enough for a small dog, and a tablespoon is enough for a medium or large dog. Yogurt is a treat, and the AKC's general rule is that treats of all kinds together should stay under 10 percent of your dog's daily calories, while the ASPCA advises keeping snacks to no more than 5 percent, so yogurt is best kept well inside that range. The right amount depends on your dog's size, activity level and health, and the first serving should always be smaller than you think is needed. Offer a teaspoon, watch your dog for a day, and only repeat it if there is no gas, no soft stools and no vomiting. There is a second reason to keep portions small, and it is fat. The AKC warns that as with any dairy product, owners have to be concerned with the fat content, because too much fat in a dog's diet can cause stomach upset or even pancreatitis, a serious and potentially fatal illness. The ASPCA makes the same point: people food tends to be high in fat and sugar, and too much fat can lead to inflammation of the pancreas that can land a dog in the hospital. A dog that is overweight, has had pancreatitis before, or takes medication that affects fat digestion should only eat yogurt if the veterinarian approves it, and only in a small amount.
Plain yogurt is at its best when it is served simply, and the AKC names two serving ideas that turn a spoonful into something a dog really enjoys. Spoon plain yogurt into silicone popsicle molds or ice cube trays and freeze it, and you have a cool treat for a warm day. Fill a stuffable chew toy with yogurt and freeze it, and you have a long lasting enrichment treat that keeps a dog busy. Both ideas work because freezing slows a dog down, which matters for dogs that gulp. You can also stir a spoonful into your dog's dinner, use it to hide a pill, or spread a thin layer on a lick mat. What you should not do is buy frozen yogurt from a shop and share it: shop-bought frozen yogurt is usually full of sugar and often contains flavoring or xylitol, so it is not for dogs. Freeze plain, unsweetened yogurt yourself instead. The same goes for yogurt covered pretzels, yogurt drops and yogurt coated treats sold for dogs: check the label, because many of them are sweetened, and a plain spoonful from the tub is cheaper and safer than any of them.
Yes, puppies can eat a tiny amount of plain, unsweetened yogurt. Offer a teaspoon, watch for loose stools or gas, and stop if you see either. Puppies are still developing their digestion, and they are more likely to gulp, so keep the portion small and keep it plain. Never give a puppy flavored or sweetened yogurt, and never use yogurt as a replacement for puppy food or for a meal. If your puppy is on a special diet, or has had stomach trouble, ask your veterinarian before offering any new food, yogurt included. A puppy that tolerates a teaspoon of plain yogurt will usually be fine with the same small amount as an adult, but there is no need to make it a daily habit.
Yogurt is often suggested for a dog with an upset stomach, and there is a real reason for that: the live cultures in yogurt can act as a probiotic, and a healthy gut flora helps digestion. But the answer is not as simple as it sounds, because the same yogurt that helps one dog can make another dog worse. A dog that cannot digest lactose will get more gas and looser stools from yogurt, not fewer, and a dog with an upset stomach is already struggling to digest what it eats. The AKC notes there are better sources of probiotics for dogs than yogurt, and a probiotic made for dogs is a more reliable choice than a tub from the supermarket. If your dog has diarrhea or vomiting, ask your veterinarian before offering yogurt, and never use it as a treatment for an ongoing stomach problem. Yogurt is a treat for a healthy dog, not a medicine for a sick one.
Plain yogurt is safe for most dogs, but every dog is different, and a food that works for one dog may not suit another. Call your veterinarian if your dog vomits, has diarrhea or seems unwell after eating yogurt, if your dog shows signs of pancreatitis such as repeated vomiting, belly pain or loss of appetite, or if your dog has diabetes, is overweight, or has a health condition such as pancreatitis, kidney disease or a dairy allergy that affects their diet. If your dog eats yogurt sweetened with xylitol, or any yogurt with chocolate, raisins or macadamia nuts, do not wait for symptoms: contact your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. Our emergency guide covers the general steps if your dog eats something they should not have.

Behind the Yogurt verdict stand 3 listed sources: the American Kennel Club and the ASPCA. the ASPCA is the rarest of them family-wide, cited by 61 of the 84 guides. The the ASPCA entry here is Sharing is Caring, Foods You Can Safely Share with Your Pet. This page does not hold the combination alone: 43 other guides use it too. Its FAQ block answers 9 questions; 1 guides answer more, and the fullest FAQ in the section answers 10. It is a longer-than-median read at 2613 words (median 739); 1 guides exceed it. Alphabetically it comes last among the guides, after Xylitol.
Yes, most dogs can eat plain, unsweetened yogurt in small amounts. Choose a plain yogurt with live cultures, ideally Greek-style, because it has less lactose and is easier for many dogs to digest. Flavored yogurt, sweetened yogurt and any yogurt containing xylitol are never for dogs.
Yes, plain Greek-style yogurt is usually the better choice. It is strained, which removes much of the whey and with it much of the lactose, and it is higher in protein. Lower lactose means an easier time for dogs that are sensitive to dairy. It still has to be plain and unsweetened, with no added sugar or xylitol.
No. Flavored yogurt is made for people, not dogs. It usually contains added sugar, and many light or diet versions are sweetened with xylitol, which is toxic to dogs even in small amounts. Some flavors add chocolate, raisins or fruit purees, which are also unsafe. Only plain, unsweetened yogurt belongs in a dog's bowl.
A spoonful is plenty. A teaspoon is enough for a small dog, and a tablespoon is enough for a medium or large dog. Yogurt is a treat, and treats of all kinds together should stay under 10 percent of your dog's daily calories, while the ASPCA advises keeping snacks to no more than 5 percent. Start with a small amount the first time and watch your dog for a day.
A small spoonful most days is fine for a healthy dog that tolerates dairy, but it is not necessary and it should never become a daily habit for a dog that gets loose stools or gas from it. If your dog shows any digestive upset after yogurt, stop offering it. Dogs that are lactose intolerant should not eat yogurt at all.
Yes, puppies can eat a tiny amount of plain, unsweetened yogurt. Offer a teaspoon, watch for loose stools or gas, and stop if you see either. Puppies are still developing their digestion, so keep portions small and keep it plain. Never give a puppy flavored or sweetened yogurt.
Contact your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away, and do not wait for symptoms. Xylitol can cause a rapid drop in blood sugar and liver damage, and it is an emergency even in small amounts. Bring the tub with you so the vet can see the ingredient list.
Frozen plain yogurt is fine as an occasional treat, and freezing plain yogurt in molds or a stuffable chew toy is one of the best ways to serve it. Shop-bought frozen yogurt is a different product: it is usually full of sugar and often contains flavoring or xylitol, so it is not for dogs. Freeze plain, unsweetened yogurt yourself instead.
It can help some dogs, because the live cultures in yogurt can act as a probiotic, but it can also make things worse for a dog that cannot digest lactose. The AKC notes there are better sources of probiotics for dogs than yogurt. If your dog has diarrhea or vomiting, ask your veterinarian before offering yogurt, and never use it as a treatment for an ongoing stomach problem.
