Yes, most dogs can have a little plain, mild cheese as an occasional treat, and it's a brilliant training reward because dogs find it irresistible. The catch is that cheese is high in fat and salt, some dogs don't digest dairy well, and a few cheeses, blue cheese especially, should be avoided altogether. So here's how to use cheese well, which types to pick, and the one kind to keep firmly out of reach.
Is cheese actually good for dogs?
It's more of a treat and a tool than a health food, but it does bring a few things to the table.
-
Protein and calcium, plus some vitamin A and B vitamins.
-
Serious tastiness, which is exactly why it's such a useful training reward and pill-hider.
That said, let's be honest about the flip side: cheese is high in fat and salt, so it's a treat rather than something your dog needs. Everyday nutrition is the job of a complete diet, which is what our dog food recipes are built to deliver. Cheese just earns its place as the occasional high-value extra.
The lactose question: it's usually the fat and salt that matter more
Here's a reframe worth having. As dogs grow up, they make less lactase, the enzyme that breaks down lactose (the natural sugar in milk), so dairy can give some dogs a gurgly tummy (Blue Cross). True lactose intolerance does happen, and those dogs need dairy kept out of their diet.
But here's the bit people miss: hard, aged cheeses like cheddar and parmesan are naturally very low in lactose, because most of it breaks down as the cheese matures. So for a lot of dogs, the bigger issues with cheese are the fat and the salt, not the lactose. If you want the gentlest, lowest-fat, low-lactose dairy option, cottage cheese is the one to know about, and we cover it properly in our guide to dogs and cottage cheese.
The big one: never feed your dog blue cheese
This is the section to take seriously. Blue cheeses like stilton, Roquefort, and gorgonzola should be avoided full stop. The mould that gives them their veins, Penicillium roqueforti, can produce a substance called roquefortine C that dogs are particularly sensitive to.
In plain terms, blue cheese can cause vomiting, diarrhoea, a high temperature, muscle tremors, and, in more serious cases, seizures, and the risk goes up the more your dog eats (Blue Cross). It's not worth the gamble. Keep blue cheese well out of reach, off the cheeseboard edge, and out of the bin, and if your dog does get into some, call your vet promptly rather than waiting to see what happens.
It's worth knowing where blue cheese hides, too. It turns up in salad dressings, dips, sauces, and on the leftovers people scrape into the dog's bowl as a treat. So it's not just the wedge on the board to watch, it's the blue cheese dressing on a salad or the dollop on a steak. When in doubt, if it smells of stilton, it isn't for the dog.
Other cheeses and add-ins to avoid
Blue cheese isn't the only one to skip. A quick scan of what else to leave off the menu:
-
Anything flavoured with garlic, onion, or chives, all of which are toxic to dogs.
-
Very salty or heavily processed cheeses, including cheese strings, which pack salt and additives.
-
Cream cheese or soft spreads with added flavourings, which often hide herbs, garlic, or extra salt.
The simple rule that keeps you right: plain and mild is the way to go.
Best cheeses to share, if you're going to
If you're going to share, a bit of "which one" guidance helps. Fed in tiny amounts, the better picks are the lower-fat, plain ones.
-
Plain cottage cheese or a little plain mozzarella, both lower in fat. We cover the details in our dogs and cottage cheese guide.
-
Mild cheddar in small cubes, a classic training reward that's naturally low in lactose.
-
Plain, unflavoured soft cheese, in small amounts.
Lower fat and plain wins every time, and portions should stay tiny whichever you choose. A handy trick for training is to cut cheese into pieces no bigger than a pea, so a pocketful of rewards adds up to barely any cheese at all. Even the lower-fat options still count towards the day's calories, so the smaller you cut, the more rewards your dog earns without the waistline noticing.
Fat, salt, and the dogs who should skip cheese
Cheese suits a lot of dogs in small amounts, but some are better off without it.
-
Overweight dogs. Cheese is calorie-dense, and the weight creeps on quickly.
-
Dogs prone to pancreatitis, which is painful inflammation of the pancreas often linked to fatty foods, so high-fat treats are a genuine risk (PDSA).
-
Dogs on low-salt diets for heart conditions.
-
Dogs with a dairy allergy or sensitive digestion, who often do better with none. Our guide to the best dog food for sensitive stomachs is the place to go for those dogs.
If your dog falls into any of these groups, check with your vet before sharing cheese.
How to serve cheese safely
Used well, cheese is one of the handiest treats going. Keep it simple.
-
Choose a plain, mild, lower-fat cheese.
-
Offer a small cube or a few shreds, no more.
-
Use it as a high-value training reward, or smear a little squeezy cheese into a Kong or on a lick mat, and freeze it to make it last.
-
Keep an eye on the daily total, treats included.
One useful aside: if you use cheese to hide tablets, check with your vet first, because the calcium in dairy can stop some antibiotics from being absorbed properly. And on amounts, the rule of thumb is that treats should be no more than about 10% of your dog's daily food, with complete meals doing the rest (UK Pet Food; PDSA). We won't give a gram count, since the right amount depends on your dog's size, so lean on the feeding guide on their food and your vet.
A brilliant training treat, not a daily habit
Cheese genuinely earns its keep as an occasional high-value reward, the sort of thing that turns shaky recall into a reliable comeback. But the goodness that keeps a dog thriving comes from complete, balanced meals, with treats playing a small supporting role. Save the cheese for the moments that matter, and let the proper food do the work.
If you want our honest steer, we'd reach for one of our natural dog food recipes for everyday meals and natural dog treats. And if you're working through the "can my dog eat this?" list, our guides to dogs and prawns, dogs and melon, dogs and peppers and dogs and apples cover plenty more.
Cheese FAQs
Can dogs eat cheddar cheese?
Yes, mild cheddar in small amounts is one of the better choices, and it's naturally low in lactose. Small cubes make a perfect training reward, just keep the quantity tiny because it's still high in fat.
Can dogs eat blue cheese?
No. The mould in blue cheeses like stilton and Roquefort can make dogs seriously unwell, with the risk rising the more they eat. If your dog gets hold of some, call your vet promptly.
Is cheese bad for dogs?
Not in itself, in small amounts, but it's high in fat and salt, so it's an occasional treat rather than an everyday food. Overweight, pancreatitis-prone, or dairy-sensitive dogs are better off skipping it.
Can dogs eat cheese if they're lactose intolerant?
Best avoided. While hard cheeses are low in lactose, a truly lactose-intolerant dog should have dairy kept out of their diet, so check with your vet rather than risking an upset tummy.
Can puppies eat cheese?
A tiny piece can work as a training treat once a puppy is weaned, but their nutrition should come from a complete puppy food. Introduce it slowly and watch for any tummy upset.
How much cheese can a dog have?
Only a little, a small cube or a few shreds, kept within the 10% treat allowance and scaled to your dog's size. Daily cheese isn't a great habit because the fat adds up.
Can dogs eat cream cheese or cheese strings?
Plain cream cheese in a tiny amount is usually OK, but skip flavoured versions with garlic, onion, or herbs. Cheese strings are best avoided too, as they're salty and processed.
Is cheese OK for hiding my dog's tablets?
Often yes, but not with every medicine. Some antibiotics bind to the calcium in dairy and work less well, so check with your vet before using cheese as a pill-hider.
