Pumpkin for dogs is a safe, mild fiber add-in for most dogs, but its fiber content is low. Tufts' Petfoodology team lists about 0.4 g and 5 calories per tablespoon of canned pumpkin. The Merck Veterinary Manual lists 1 to 4 tablespoons per meal for constipation. Use 100% pumpkin, not pie filling, which can have over three times the calories. Call your vet if diarrhea lasts over two days, Cornell advises.
Key points
- One tablespoon of psyllium husk provides about as much fiber as 9 tablespoons of canned pumpkin, based on the per-tablespoon amounts in Tufts' fiber table.
- Plain canned pumpkin has 83 calories per cup, while pumpkin pie mix has up to 281 because of added sugar, according to Tufts nutritionists.
- Make sure your dog drinks enough water before adding fiber. This helps prevent fiber from packing into a constipated colon, as the Merck Veterinary Manual advises.
- Call your vet if your dog has not had a bowel movement within 48 to 72 hours of the last one, advises VCA Animal Hospitals.
- Any puppy or unvaccinated dog with vomiting and diarrhea needs a parvovirus test, according to Cornell. Do not try pumpkin first.
Pumpkin for dogs: safe, but low in fiber
Pumpkin is a good food option for most dogs, but it adds little fiber. Vegetables such as pumpkin and green beans are healthy and safe for most pets. However, their fiber content varies and is typically low, according to Tufts' Petfoodology article on fiber. For a broader look at digestion, see our guide to dog gut health.
What does pumpkin do for dogs?
Pumpkin adds two kinds of fiber, both in small amounts. Soluble fiber dissolves in water and forms a gel that slows digestion and draws water into the gut. Insoluble fiber increases stool volume and frequency, Tufts explains. A tablespoon of canned pumpkin contains 0.4 g of total fiber, of which only 0.1 g is soluble.
The evidence supports fiber in general, not pumpkin specifically. None of the veterinary sources used for this article cite a clinical trial of pumpkin itself. The dog study referenced in Tufts' fiber article found benefits with a common human psyllium supplement, which provides a different type of fiber.
What nutrients does pumpkin have?
Besides a little fiber, plain canned pumpkin is best known for vitamin A. University of Illinois Extension describes a half cup of 100% canned pumpkin, with no added sugar, as an excellent source of vitamin A.
A half cup equals 8 tablespoons, so the tablespoon or two added to your dog's meal provides only a small share of that vitamin A. Think of pumpkin as a food extra, not a vitamin supplement.
How much pumpkin to give a dog
Give 1 to 4 tablespoons of canned pumpkin per meal, starting at 1 tablespoon. This is the range the Merck Veterinary Manual lists for pumpkin as an added source of fiber for constipation. You can mix it into canned food.
Merck does not list pumpkin amounts by body weight. However, the same list notes that cats and small dogs need smaller amounts of psyllium. Keep a small dog at the low end, and ask your vet how far up the range a larger dog should go. The following table shows what each amount adds per day across two meals, calculated using the 0.4 g of fiber and 5 calories per tablespoon in Tufts' fiber table.
| Canned pumpkin per meal | Fiber per day (2 meals) | Calories per day (2 meals) |
|---|---|---|
| 1 tablespoon | 0.8 g | 10 |
| 2 tablespoons | 1.6 g | 20 |
| 3 tablespoons | 2.4 g | 30 |
| 4 tablespoons | 3.2 g | 40 |
For a toy breed or a puppy, ask your vet before adding pumpkin.
How to start pumpkin
- Make sure your dog drinks enough water. Merck advises that animals be well hydrated before adding fiber to reduce the risk of it packing into a constipated colon.
- Start at the low end: 1 tablespoon per meal. Tufts advises adding fiber gradually, over a few days to weeks, with your vet's input.
-
Mix it into the meal. Merck notes that owners can add pumpkin to canned food.
Can I give my dog pumpkin every day?
Pumpkin can fit into your dog's daily meals if you count it as an extra. Even 4 tablespoons of canned pumpkin contain only about 20 calories. That said, treats and other extras combined should account for less than 10% of total daily calories to avoid unbalancing the diet, according to Tufts' article on pumpkin. If your dog needs fiber every day, pumpkin provides relatively little, as the comparison below shows.
Can pumpkin help an overweight dog?
Plain pumpkin is a low-calorie extra, but it is not a weight-loss plan on its own. Tufts' fiber table lists about 5 calories per tablespoon of canned pumpkin, making a frozen cube of plain pumpkin a light treat for an overweight dog. Pumpkin pie mix, by contrast, contains up to 281 calories per cup because of added sugar, which can contribute to weight gain, Tufts' article on pumpkin warns.
Pumpkin is often suggested to help an overweight pet feel fuller. The same Tufts article cautions that this may not help and could cause problems in some cases. Extra fiber may reduce the amount of protein and other nutrients a pet absorbs from its food. Count every cube toward the 10% limit for extras, and ask your vet for a weight-loss plan before adding fiber for weight loss.
Pumpkin vs other fiber sources
Tufts' fiber table shows how little fiber a tablespoon of pumpkin provides compared with other common fiber sources.
| Fiber source (1 tablespoon) | Calories | Total fiber |
|---|---|---|
| Canned pumpkin | 5 | 0.4 g |
| Wheat bran | 8 | 1.6 g |
| Oat bran | 14 | 0.9 g |
| Inulin | 5 | 2.5 g |
| Psyllium seed husk | 17 | 3.5 g |
One tablespoon of psyllium husk provides about as much fiber as 9 tablespoons of canned pumpkin. Tufts estimates that a medium-sized dog would need nearly 12 cups of pumpkin a day to match the fiber in one fiber-rich therapeutic diet. If your dog needs fiber regularly, ask your vet about a therapeutic diet or fiber supplement, such as purified cellulose, wheat bran, inulin, or psyllium.
Canned pumpkin, pie filling or fresh pumpkin: what to buy
Choose plain canned pumpkin with only pumpkin on the ingredient list, ideally with no added salt. Skip pie filling and anything labeled sugar-free.
Is canned pumpkin or pumpkin puree better for dogs?
Neither is better: they are the same product when the label lists only pumpkin. Check the ingredient list rather than relying on the name on the front of the can.
Use this label check while shopping. The calorie and sodium figures come from Tufts' article on pumpkin.
| On the label | Pick | Why it matters |
|---|---|---|
| Ingredients | Pumpkin only | Pumpkin pie mix has up to 281 calories per cup because of added sugar, against 83 for plain canned pumpkin. |
| Sodium | No salt added | Some canned pumpkin has nearly 600 mg of sodium per cup, against 12 mg in unsalted cans. |
| Sweeteners | Nothing labeled sugar-free | Xylitol, found in gum, candy and baked goods, can cause low blood sugar and liver damage, warns the ASPCA. |
Can dogs eat pumpkin pie filling?
Not as a pumpkin source. Pie filling is a different food. Its added sugar can bring more than three times the calories of plain canned pumpkin, and it is seasoned for pies. Check the label before adding any pumpkin product to your dog's bowl.
Fresh pumpkin
If you use fresh pumpkin, serve the flesh cooked, plain, and mashed. Leave out the stem, skin, and seeds.
How to store leftover pumpkin
Spoon leftover pumpkin into an ice-cube tray, measuring one tablespoon per cube, and freeze it. Refrigerate an opened can only for as long as the label recommends.
Pumpkin for dog diarrhea: what it can and can't do
Pumpkin adds a little soluble fiber, which draws water into the gut and forms a gel. A tablespoon contains only 0.1 g of soluble fiber, according to Tufts' fiber figures, so expect little. It is an option only for one mild bout in an adult dog that eats, drinks, and acts normally.
The “Pumpkin or vet?” table below follows Cornell's advice on diarrhea.
| What you see | What to do |
|---|---|
| One mild bout of loose stool in an adult dog that eats, drinks, and acts normally | Plain pumpkin is an option. Keep fresh water available and skip extra treats and rich food until the stool is normal. |
| Loose stool for more than two days | Call your vet. |
| Loose stool with black or tarry stool, fresh blood, no appetite, lethargy or vomiting | Call your vet. Do not wait to see if pumpkin works. |
| A puppy or unvaccinated dog with vomiting and diarrhea | Call your vet for a parvovirus test and skip the pumpkin. Parvovirus commonly affects puppies between 6 weeks and 6 months, and early treatment improves the chance of recovery, says Cornell's parvovirus page. |
How much pumpkin do I give a dog with diarrhea?
The sources cited here do not specify an amount for diarrhea. Merck's 1 to 4 tablespoons per meal is listed for constipation. If your vet agrees that pumpkin is worth trying, start at the low end of the chart above.
How fast does pumpkin work for dog diarrhea?
None of the sources cited here give a timeline, so follow the guidance on when to call your vet instead. If loose stool lasts more than two days or comes with any warning sign in the box, call your vet rather than giving more pumpkin. For other steps, see how to firm up loose stool.
Pumpkin for dog constipation: water first, then fiber
Pumpkin is one of the added fiber sources the Merck Veterinary Manual lists for constipation, at 1 to 4 tablespoons per meal. Make sure your dog drinks enough water first. Call your vet if your dog has not had a bowel movement within 48 to 72 hours of the last one, as VCA Animal Hospitals advises.
How much pumpkin should I give my dog for constipation?
Start at the low end of Merck's range, 1 tablespoon per meal, once your dog is drinking enough water. Merck advises that animals be well hydrated before adding fiber to reduce the risk of fiber packing into a constipated colon. VCA adds two steps: encourage your dog to drink, and limit access to bones.
Most of pumpkin's fiber is insoluble, which increases stool volume and frequency, according to Tufts' fiber article. Still, a tablespoon contains only 0.4 g of total fiber.
Signs of constipation in dogs
Constipation means passing stool infrequently or with difficulty. VCA lists these signs:
- Repeated unsuccessful attempts to pass stool
- Scooting, frequent squatting, or circling
- A painful belly
- Decreased appetite, vomiting, and weight loss
A constipated dog may also pass small amounts of watery stool or stool with mucus, which can be mistaken for diarrhea. Check with your vet before treating apparent loose stool in a dog that has been straining.
How long can a dog go without pooping?
Call your vet if your dog has not had a bowel movement within 48 to 72 hours of the last one, VCA advises. If you are unsure, or your dog also stops eating, vomits, or loses weight, call your vet.
Common causes of constipation
VCA lists bones or plant matter, dehydration, too little exercise, and some medicines as causes. Do not give your dog a laxative or any other medicine unless your vet tells you to.
Pumpkin treats and holiday safety at Halloween and Thanksgiving
The simplest pumpkin treat is a frozen cube of plain canned pumpkin, counted toward your dog's daily amount. During pumpkin season, watch for hazards around the treats: lit jack-o'-lanterns, xylitol, chocolate, and onions and garlic in holiday food.
Are pumpkin treats safe for dogs?
Treats made from plain pumpkin are suitable for most dogs, as long as the recipe contains no xylitol and you count them toward the daily amount. This one-ingredient treat keeps things simple:
- Spoon plain canned pumpkin into a silicone tray, measuring one tablespoon per cube.
- Freeze the tray.
- Serve one cube with a meal, and count it toward the amount in the chart for that meal.
If a recipe includes peanut butter, check the label for xylitol. Cornell's page on xylitol notes that it is found in some peanut butters and other sugar-free foods. In dogs, even a small amount can cause very low blood sugar within 30 to 60 minutes. For brands and labels, see which peanut butters are safe for dogs.
For more variety, try these two easy pumpkin treats, starting with a variation on the frozen cube.
Frozen pumpkin and peanut butter cubes
- Spoon plain canned pumpkin into a silicone tray, measuring one tablespoon per cube.
- Add a small dab of peanut butter with no xylitol listed on the label to each cube.
-
Freeze the tray, and give one cube as a treat.
Two-ingredient pumpkin and oat bites
- Grind plain rolled oats into a fine flour in a blender.
- Stir the oat flour into plain canned pumpkin, a spoonful at a time, until the dough holds its shape.
- Roll out the dough, cut it into small pieces, and bake them on a lined tray until firm and dry.
-
Let the bites cool completely, and store them in a sealed container in the fridge.
Count each treat toward your dog's extras for the day, which should account for less than 10% of total calories, according to Tufts' article on pumpkin. While your dog has loose stool, skip extra treats and rich foods such as peanut butter until the stool returns to normal, as Cornell advises.
Leave out yogurt and milk if your dog has loose stool. Milk and other dairy products can cause diarrhea or other digestive upset, the ASPCA notes.
Can I give my dog pumpkin pie?
Skip it. Pumpkin pie is sweetened, and desserts containing artificial sweeteners such as xylitol can cause low blood sugar, liver damage, or even death, the ASPCA's Thanksgiving tips warn. Give a cube of plain pumpkin instead.
Pumpkin season safety
Candles: Keep lit jack-o'-lanterns out of reach. A pet could knock one over and start a fire, the ASPCA's Halloween tips warn.
Xylitol: Sugar-free candy can cause serious problems. Desserts containing xylitol can cause low blood sugar, liver damage, or even death.
Chocolate: Chocolate in all forms can be very dangerous for dogs.
Onions and garlic: Both are common in Thanksgiving dishes and can be toxic to pets, the ASPCA's Thanksgiving tips note. If you share a small bite of turkey, make sure it is boneless and fully cooked.
If your dog eats something dangerous, note the amount, keep the packaging, and call your vet or ASPCA Animal Poison Control at (888) 426-4435. The service is open 24 hours a day, 365 days a year. A consultation fee may apply.
Pumpkin, fiber and your dog's daily digestive routine
Pumpkin provides a little fiber, but it is not a probiotic. Cornell's page on probiotics explains that probiotics boost healthy gut bacteria that help digest food. Prebiotics are fibers that probiotics feed on.
A daily probiotic can be one part of a healthy dog's routine, separate from pumpkin. HolistaPet makes Probiotics for Dogs, soft chews that support normal digestion as part of daily care. Visit the product page for label details on HolistaPet's probiotic soft chews, and ask your vet whether a daily probiotic is a good fit for your dog.
