Cucumbers are a safe food for dogs to snack on, in moderation. Not all dogs enjoy the texture or taste though, and you may find your pup snubs the offer in favour of their usual treats instead. Cucumbers can have an unpredictable amount of bitterness, especially in the skin, because of a factor called cucurbitacin. This may be more or less influential in the fruit’s flavour, depending on where the cucumbers grew and the local climate.
Cucumbers also have many health properties that you may be familiar with from your own beauty and/or health routines and dogs can benefit from these as well. Read on to learn all about the benefits of cucumbers for your pooch.
Nutrition facts about cucumbers for dogs
The cucumber’s scientific name is Cucumis sativus and it is a member of the gourd family. Cucumbers grow on a vine, which produces yellow flowers prior to forming the edible fruits we enjoy. There are tons of different varieties of cucumbers and they come in all sizes, shapes and in varying shades of greens and yellows. Cucumbers contain a large amount of water making up approximately 95 percent of their weight, giving them that refreshing juicy crunch.
They also contain potassium, phosphorus, calcium and magnesium, all of which are vital minerals used in normal cellular function throughout the body. They contain fibre, especially in the skin, which helps to move food through the digestive tract, bulks up the poo and prevents constipation.
They are very low in calories, largely because of their water content and can be a great way to provide small treats to your pup without adding a lot of extra calories to their daily intake. They do not contain significant amounts of protein or fat, however, which means that while they make a good refreshing snack, they do not provide much energy to the body. On days when your dog is very activeopens in a new tab, they will need a treat loaded with more protein and fat to keep up with their needs.
Are cucumbers good for dogs?
Cucumbers are good for dogs as the occasional small treat and may have some benefits to the skin when applied topically as well. It is important to remember that dogs need to get the bulk of their diet from a balanced dog food in order to get all of the nutrients they need. Be sure your dog’s primary food source is complete and balancedopens in a new tab for daily nutrition and that treatsopens in a new tab make up less than 10 percent of their total daily intake.
Because cucumbers have such a high water content and low-calorie count, if a dog fills up on lots of cucumbers and doesn’t eat enough of their other food, they will miss out on important nutrients as well as calories they need to maintain a healthy weight. As an occasional treat, cucumbers can be a fun way to introduce novelty and keep your pup’s snacks exciting. Here are some ways cucumbers can provide health benefits to your pup.
Hydration: cucumbers are about 95 percent water. So, if you have a pup who loves to crunch on a juicy cucumber, you can use this treat to help keep your pup cool and hydrated on hot days. Pop some cucumber slices in the fridge for a few hours before heading outside and let your pup snack while keeping cool and getting a burst of hydration at the same time. Be sure to provide plenty of water as well, of course.
Minerals: cucumbers contain many important minerals that are necessary for normal cellular function in the body. This includes potassium, phosphorus, calcium and magnesium. These are all contained within your dog’s primary diet as well, so your pup likely gets plenty of these already. These minerals have critical roles in the body from heart function to healthy bones, muscles and nerves.
Fibre: like many vegetables, cucumbers contain fibre, especially in their skin. Fibre is a form of carbohydrate that can help to bulk up poo and prevent constipation. Cucumbers are not as high in fibre as some other vegetables and fruits, so if you are trying to treat or prevent constipation, there may be better choices for your pup.
Low in calories: cucumbers are mostly water, so you can imagine that they are quite low in calories. This can make them a good snack choice if your pup is overweight and you need to avoid high-calorie treats. Keep in mind that all treats should be no more than 10 percent of your dog’s total daily intake, but if you need to closely monitor your dog’s intake, choosing fruits and veggies that are low in calories can be a great way to continue providing fun treats without adding too many calories.
Soothes the skin: when the cucumber flesh is applied to the skin, it is thought to have cooling and soothing properties. It has been used for centuries in traditional medicine to treat sunburns, thermal burns, itchy skin and puffy eyes. If your pup tolerates it, you can try using it for these purposes, too, by gently holding a slice of cucumber over areas of mild redness or itchinessopens in a new tab on the skin. Be sure not to put it on any open wounds or serious injuries because it may be painful and/or introduce infection.
Can dogs eat any part of the cucumber?
In theory, yes, dogs can eat any part of the cucumber and even any part of the cucumber plant without having to worry about toxins. The whole plant, as well as the fruit, including the skin and seeds, are non-toxic to dogs. That does not necessarily mean your dog will eat any part of the cucumber, though.
Remember that cucumbers contain cucurbitacins, the compound that creates a bitter taste. This may be more or less present in the fruit itself and the skin is usually the most bitter part of the fruit. The plant is even more chock full of cucurbitacins, so the stems and leaves of the plant are especially bitter and likely very unappetising to your pup. If you are trying to tempt your dog to try a cucumber, try peeling off the skin first and offering them just the pale fleshy part of the cucumber to see if that is more enticing.
Are cucumbers completely safe for dogs?
Cucumbers are quite safe for dogs. There are a few nuances to consider though and it is important to double-check with your veterinarian if your dog has any special diet considerations or underlying medical problems that may affect their snack options.
Moderation is key
The biggest takeaway is to remember that cucumbers should be offered in small amounts as an occasional snack. They do not contain enough calories or enough of the main nutrients dogs need to be a main part of their diet. They shouldn’t fill up on cucumbers at the expense of eating their more balanced dog food.
Risk of intestinal blockage
Remember to cut the cucumber into bite-sized pieces for your dog. If your dog were to swallow a large chunk of cucumber whole, there could be a risk of obstruction in the digestive tract. This would happen if a large piece got stuck within the stomach or intestines and could not pass, requiring emergency surgery. It would be rare for this to happen from a cucumber, but some dogs do not chew their food thoroughly and swallowing a large piece whole could make that a possibility.
Diuretic properties
There are known diuretic effects from plants in the Cucumis family, including cucumbers. This means that compounds in the cucumber stimulate the body to produce and excrete urine. This is not dangerous to your dog, but it may be risky for your sofa.
If your dog eats a bunch of cucumbers, they may need more frequent walks and opportunities to wee throughout the day to avoid having accidents in the house. And try to remember not to feed them a bunch of cucumbers right before bed or a long car trip.
The bottom line: can dogs eat human food?
While there are many human foods that are safe for dogs and may be beneficial to their health, there are some that can be toxic. Keep in mind that dogs and humans have different nutritional needs and for this reason, it is important to feed your dog a diet that is complete and balanced to meet their daily nutritional needs. In most cases, a commercially available dog food is going to be the best option for being healthy, affordable and easily accessible.
If your dog has specific health problems, your vet might recommend a prescription diet instead. It is best to save human food for the occasional treat and to make sure that anything you feed your pup is safe for them. Be especially wary of cooked foods that may contain multiple ingredients because certain added seasonings or fats might not be safe for your pup. Stick with plain and simple snacks that you know are non-toxic.
Other vegetables that are safe for dogs
There are many other fruits and veggies that you can consider using as treats for your pup as well. It can keep things interesting for your pup to have a larger variety of treats and to be able to try things you are snacking on too. Here are some other options to consider adding to your pup’s menu:
Pumpkin opens in a new tabcontains lots of fibre, antioxidants, vitamin C and beta-carotene, along with many other important health benefits.
Kaleopens in a new tab contains tons of nutrients including vitamin A, vitamin E, folate, manganese, thiamin, iron, potassium and phosphorus as well as antioxidants.
Carrots contain vitamins C and K, potassium, magnesium, phosphorus and lutein, along with antioxidants and fibre.
Other foods that are potentially dangerous
Some common human foods can be toxic to pups so it is always a good idea to double check before offering something new to your dog. For example, did you know the following foods are not considered safe for dogs?
Avocadoopens in a new tab contains a compound called persin, which is a mild toxin for dogs and may cause vomiting and diarrhoea.
Xylitol is an artificial sweetener used in many human foods as well as medications. If dogs ingest it, it can cause very serious low blood sugar and/or liver failure. Hops used in beer brewing can be very toxic if ingested by dogs. They can cause agitation, seizures, vomiting and very high body temperatures, which can be deadly.
