Say Goodbye to Dog Hairballs

I’m a licensed veterinarian practicing in a busy small-animal clinic in Texas, and most people are surprised when I tell them dogs can get hairballs, too. They’re far less common than in cats, but I’ve treated more than a few dogs who hack, gag, or bring up clumps of matted hair after heavy shedding seasons.

The good news is that many mild cases can be eased at home with simple, safe steps. The bigger challenge is knowing which situations you can handle on your own and which really do need a visit to the clinic.

I’ll walk you through what I routinely recommend to my own clients and what has actually worked in real households—not just in theory.

What hairballs in dogs usually look like

Dogs don’t usually vomit tidy little cigar-shaped hairballs like cats. More often I see:

• gagging or retching without much coming up
• coughing that owners mistake for a respiratory problem
• occasional vomiting with clumps of hair mixed in the stool or vomit

I remember a golden retriever I saw one spring, who was coming in every couple of weeks for “random vomiting.” The real issue turned out to be intense seasonal shedding. He was swallowing a remarkable amount of hair during self-grooming and from licking itchy skin. Once we addressed the hair and the itch, the “mystery vomiting” stopped.

First, reduce the amount of hair your dog swallows.

That is the part most people underestimate.

In my experience, grooming does more to prevent hairballs than any oil, paste, or supplement. With double-coated breeds, a few minutes of brushing doesn’t reach the dense undercoat that mats and sheds.

For heavy shedders, I usually recommend a thorough brushing session several times a week, sometimes daily during seasonal coat blows. A client with a husky mix told me she thought she was brushing regularly — then we spent fifteen minutes with a proper undercoat rake in the exam room, and we filled half a trash bag with loose hair. The dog’s gut immediately had less hair to manage afterward, and the retching episodes dropped off.

Bathing with a gentle shampoo can also loosen dead hair so it doesn’t end up swallowed. Just don’t over-bathe; dry skin leads to itching and more licking, which brings the problem right back.

Simple dietary lubrication can help.

For dogs that occasionally have hair pass through the gastrointestinal tract, small amounts of dietary lubrication can make a difference.

A tiny amount of healthy fat added to food — for example, a teaspoon or so of plain canned pumpkin or a splash of fish oil — can help hair move along the intestines more smoothly. I stress “small amounts” because I’ve seen well-meaning owners dump large amounts of oil over the bowl and then deal with diarrhea for the next two days. More is not better here.

There are also hairball gels marketed for cats. I have, on occasion, advised using them in dogs as well, but only after checking the ingredients and confirming the dog has no history of pancreatitis or food sensitivities. If your dog has had stomach, pancreas, or chronic diarrhea issues, skip this step and call your vet first.

Fiber often helps more than people expect

That is one of my favorite quiet fixes.

Hair itself is not toxic. The issue is that it tends to clump. Fiber bulks up the stool and helps trap hair so it can exit normally rather than accumulate in the stomach.

Plain canned pumpkin (unsweetened), small amounts of cooked green beans, or a veterinarian-recommended fiber supplement can all do the job. I’ve had great luck, particularly with pumpkin, in small dogs who constantly lick themselves. One older Shih Tzu in my practice had recurring constipation and hair ingestion from chewing at her coat. Adding a spoonful of pumpkin daily made her stool softer, and her owner swore the gagging spells practically disappeared.

Manage the underlying itch or anxiety.

Dogs don’t usually sit around meticulously grooming like cats. If they’re licking enough to create hairballs, there’s almost always a reason: allergies, fleas, skin infections, boredom, or anxiety.

One of the most common mistakes I see is treating only the hairball, not the cause of the licking.

A young lab I saw last summer had developed frequent retching, and the owner was trying coconut oil, butter, and every internet trick they came across. The real problem was severe seasonal allergies, which made the dog constantly chew at his sides. We addressed the allergies, reduced licking, and resolved the “hairball” problem without any special remedy.

If your dog is constantly licking or chewing, home remedies alone usually won’t solve things. That pattern needs a medical conversation.

What I don’t recommend people try at home

There are a few things I consistently advise against:

• forcing mineral oil or straight petroleum jelly by mouth
• giving human laxatives
• using large amounts of butter or cooking oil
• assuming repeated gagging is “just hairballs.”

I’ve treated more than one dog for aspiration pneumonia after an owner attempted to syringe mineral oil into the mouth. If it goes down the wrong pipe, the lungs cannot clear it well. That’s not a risk worth taking for a mild hairball issue.

When home remedies aren’t enough

There are clear red flags I ask owners to watch for:

• Repeated vomiting or inability to keep food down
• a swollen or painful abdomen
• lethargy, weakness, or obvious distress
• constipation lasting more than a couple of days
• coughing that doesn’t match typical gastrointestinal gagging

Those are no longer “hairball problems.” Those are “go-to-your-vet” problems.

True intestinal blockages from hair are uncommon in dogs, but I’ve seen them, particularly in long-haired breeds who ingest not only their own fur but also carpet fibers, toy stuffing, or grooming wipes. In those cases, waiting for home remedies can prolong discomfort and turn a manageable situation into a surgical procedure.

My bottom-line advice after years of seeing this

If your dog occasionally retches after swallowing hair, start with the basics: better grooming, a bit more fiber, and modest dietary lubrication. These are the same practical steps I suggest across my own exam table, and in many mild cases, they make a noticeable difference within a week or two.

But don’t ignore the bigger picture. Hairballs in dogs are rarely random. They’re usually a clue that your dog is shedding heavily, licking too much, or dealing with skin, allergy, or stress problems that deserve attention.

That balanced approach keeps most dogs comfortable and keeps hair where it belongs: in the brush, not in the stomach.
