Can Dogs Eat Pickles?

1. Put out fresh water. Salt poisoning is unlikely while a dog's body is working normally and it can drink fresh water freely, according to Merck.
2. Find the jar and read the ingredients. Look for onion, garlic, chives, leeks and hot peppers.
3. Estimate the amount. How many pickles or slices, and whether your dog drank any brine. Note your dog's weight.
4. Call your vet or a poison line if your dog ate more than a nibble, drank brine, is small or has heart disease, or if the jar lists any onion-family ingredient. For the onion family, VCA Animal Hospitals advises calling your vet or Pet Poison Helpline right away.
5. Keep salt out of any home remedy. Table salt is sometimes suggested for making a dog throw up, and Merck warns it can cause salt poisoning by itself.

Go to an emergency vet now if your dog vomits repeatedly, trembles, walks as if drunk, has a seizure, has pale gums or red-brown urine, or collapses.

Merck gives numbers for salt itself. Signs of salt poisoning in dogs can appear after about 2 to 3 grams of salt per kilogram of body weight, and the reported lethal dose is about 4 grams per kilogram.

These figures are for salt. How much salt sits in one pickle depends on the brand and recipe, so the table cannot be turned into a count of slices. Bring the jar, or read out the sodium line on the label, and your vet or the poison line can work out where your dog stands.

The onion family has its own numbers. Merck reports signs in dogs after 15 to 30 grams of raw onion per kilogram, and garlic is 3 to 5 times more toxic than onion. VCA adds that dried and powdered onion and garlic, the kind in seasoning blends, are more concentrated than fresh. With a garlic dill pickle you rarely know how much garlic went into one spear, which is why an onion-family ingredient on the label is a reason to call. Can dogs eat onions? explains that risk in full.

Two groups need extra care. Small dogs take in more salt per pound from the same slice. And dogs with heart disease can hold on to fluid after a lot of sodium, according to the FDA.

The cucumber part is not the worry. Cucumber skin and seeds are not toxic to dogs; the brine and whatever went into it are. Can dogs eat cucumbers? covers the plain vegetable.

Salt. Merck describes vomiting within several hours of a large salt intake, followed by weakness, diarrhea, muscle tremors, wobbly walking and seizures. Severe cases can lead to brain swelling, coma and death. A dog that ate a little and is simply thirstier than usual is showing the mild end of this.

Onion or garlic. Stomach upset can come early, but the blood damage runs on a slower clock. Merck says the changes in red blood cells start within 24 hours, peak around 72 hours, and the cells typically break down 3 to 5 days after the dog ate it. The ASPCA names the compound in onion, N-propyl disulfide. Between the ASPCA and Merck, the signs to watch for are:

• weakness and low energy
• pale gums
• panting or fast breathing, with a fast heart rate
• blood in the urine, or red to brown urine
• vomiting

A dog who ate a garlic pickle on Saturday and seems fine on Sunday may still be heading toward anemia by midweek.

Plenty of dogs do, and for many of them nothing visible happens. That does not make pickles safe for every dog or every jar. One chip for a 70-pound dog is a far smaller dose than the same chip for a 10-pound one. Brands differ a lot in salt and seasoning. A dog with a full water bowl handles salt better than one with no water nearby. A plain dill slice is a different food from a garlic dill spear. And onion-family damage shows up days later, when nobody links it back to the burger night. If pickles are a habit in your house, keep them to the plain kind and keep them rare, or switch to cucumber.

• Fried pickles: the batter and frying oil add fat and a separate stomach risk.
• Pickle-flavored chips and snacks: usually salty, and often seasoned with onion or garlic powder.
• Pickled ginger: a different food in a similar jar, and the AKC points out that some products contain added ingredients such as xylitol. Read the label.
• Burgers, sandwiches and potato or tuna salad with pickles: check the whole dish, which often holds onion, fatty meat or mayonnaise.
• Gherkins, cornichons and kosher dills: all cucumber pickles. The same salt and label rules apply.

A small piece of plain dill pickle is a low risk for a healthy dog, but it is still a salty snack with nothing your dog needs. Check that the jar has no onion or garlic, and do not make it a regular treat.

Yes. Brine is concentrated salt and vinegar, often with seasonings. If your dog drank more than a lick, put out water and call your vet or a poison line, especially for a small dog.

Plain dill pickles are the least risky kind, in a small piece now and then. Garlic dills are a different story because of the garlic.

Call your vet or a poison line, even if your dog looks normal. Onion and garlic damage red blood cells, and the anemia can take days to show.

Pickles with onion or garlic are worse for cats. Merck lists cats as the species most sensitive to the onion family, ahead of dogs.
