Goat milk kefir sits in an odd spot on the shelf. It isn't a complete diet, it isn't quite a treat, and most owners buy it for one of three reasons: a fussy eater, a dog or cat that needs more moisture, or a gut that's been unsettled since the last diet switch. Right now the Crosswind Farms 1 litre kefir is marked down from $14.46 to $8.81 ā 39% off, which changes the math on whether a fermented dairy topper earns a spot in your fridge. If you're already comparing toppers, it's worth browsing the wider dog health and wellness range and the cat health and wellness selection at the same time, because the alternatives price out very differently per serving.
Our top picks at a glance
For a 1 litre bottle at $8.81, goat milk kefir costs roughly 27 cents per 30 mL serving ā cheaper per serving than most single-serve broths and freeze-dried toppers. Here's how the shortlist breaks down.
- Crosswind Farms Goat Milk Kefir, 1 Litre ā best value on this list at 39% off; for multi-pet homes or a medium-to-large dog that finishes a litre inside the label's fridge window.
- The Honest Kitchen instant goat's milk powder ā for single-cat households and small dogs where a full litre of liquid would spoil before it's used.
- Caru bone broth ā the dairy-free pick; for pets that react to lactose but still need moisture and palatability on top of kibble.
- MOJO Pet Supplements probiotic powder ā for owners who want a stated CFU count and a measured scoop rather than a fermented food.
- Big Country Raw and other raw formats ā if the real goal is a higher-moisture diet rather than a topper, start with shop raw dog food instead of adding liquid to dry kibble.
How to choose a milk or broth topper
Four numbers decide whether a topper is a good buy: cost per serving, calories as a share of daily intake, lactose content, and how long the container stays good once opened. Everything else is marketing.
Cost per serving, not cost per bottle
A litre is 1,000 mL. At a common starting portion of 30 mL (about 1 oz) for a 10 lb pet, that's roughly 33 servings, or about 27 cents each at the $8.81 sale price versus about 44 cents at $14.46. A 60 lb dog taking 120 mL a day gets about eight days out of the same bottle ā closer to $1.10 daily. Run that math before you assume a litre is a bargain for your specific pet.
The 10% calorie rule
Whole goat milk runs roughly 69 kcal per 100 mL, so a 30 mL pour is about 21 kcal. Veterinary nutrition guidance from sources including the Tufts University Cummings Veterinary Medical Center holds that treats and toppers should stay under 10% of daily calories. A 10 lb cat eating around 200 kcal per day has a 20 kcal budget ā one 30 mL pour uses essentially all of it. A 60 lb dog eating 1,200 kcal has roughly 120 kcal to work with, which comfortably covers 120 mL.
Lactose tolerance
Goat milk contains roughly 4.1% lactose, slightly less than cow's milk at about 4.7%, and fermentation into kefir cuts that figure further as cultures consume the sugar. That's why some pets who get loose stool from cow dairy handle kefir. It is not a guarantee. Start with a teaspoon, not a cup.
Shelf life after opening
Fermented dairy toppers are usually sold frozen or refrigerated and have a short window once thawed ā follow the bottle's own instructions rather than a rule of thumb. In our store the single most common complaint about litre-sized liquids isn't taste, it's waste. Powders and shelf-stable broths win on this metric every time.
What the label does and doesn't promise
A kefir is a supplemental feeding product, not a complete and balanced diet, so it won't carry the AAFCO complete-and-balanced nutritional adequacy statement your main food does. Check the guaranteed analysis for protein content and fat content, then keep the main diet doing the heavy lifting. If you want a refresher on how adequacy statements work, our guide to pet food for specific needs breaks it down.
Pick 1: Crosswind Farms Goat Milk Kefir, 1 Litre ā the deal itself
At $8.81 down from $14.46, this is the lowest cost-per-serving liquid topper we're currently reviewing, saving $5.65 on a single bottle. It suits households that will actually get through a litre: two or more pets, or one dog over about 40 lbs.
What stands out is format honesty. This is a straight fermented goat milk ā no thickeners doing the work, no added sugars propping up palatability. Fermented dairy naturally supplies live cultures, though be aware that most kefirs don't print a guaranteed CFU count the way a dedicated probiotic supplement does, so if you need a specific dose, this isn't the product for that job. Goat milk also carries naturally smaller fat globules than cow milk, which is the usual reason owners find it sits better with sensitive dogs.
Practical use: pour over dry food to soften it, freeze into cubes for a summer enrichment treat, or mix into a lick mat. Our team at Ashario Pets recommends starting at one teaspoon for cats and small dogs, one tablespoon for medium dogs, and building over four to five days while you watch stool quality. Sale prices rotate, so check the Crosswind Farms goat milk kefir product page for today's price before you plan a bulk buy.
Who should skip it: pets with a confirmed dairy sensitivity, pets on a strict calorie-restricted plan, and single-cat homes where 1,000 mL is simply too much volume.
Pick 2: The Honest Kitchen instant goat's milk ā the no-waste alternative
Powdered goat's milk solves the spoilage problem: you mix only the volume you need, when you need it, and the rest stays pantry-stable. For one cat or a 12 lb terrier, that's usually the smarter purchase even though the per-serving cost is higher.

Pick 3: Caru bone broth ā for the dairy-sensitive pet
If dairy is off the table, a bone broth delivers the same two benefits owners actually want ā moisture and palatability ā with zero lactose. Broths typically run low in calories per serving while adding meaningful water to a dry-fed pet's day.
This matters more in the GTA than people expect. Winter here means months of forced-air heating, and pets on kibble often drink less than they should while indoor humidity sits low. Pet owners tell us their dogs empty a bowl faster when there's warm broth stirred through it. Look for broths without added onion, and check the sodium figure on the guaranteed analysis. You'll find broth options alongside the wet dog food selection, which is the other straightforward way to raise total moisture intake.
Pick 4: MOJO Pet Supplements probiotic powder ā when you need a real dose
If your goal is gut support rather than palatability, a labelled probiotic beats a fermented food because you know what you're giving. Supplement powders state CFU counts per scoop ā often in the billions ā while a kefir label typically doesn't.
Research indexed on NCBI/PubMed on canine and feline probiotics generally examines defined strains at defined doses, which is exactly what a measured scoop provides and a food does not. Many powders also include prebiotics such as inulin or chicory root to feed the bacteria you're adding. If a pet has ongoing digestive trouble ā not the odd soft stool after a rich chew, but a pattern ā talk to your veterinarian first. The Canadian Veterinary Medical Association is a good starting point for finding a clinic, and diarrhea lasting more than 48 hours needs a professional, not a topper. Browse the full range of dog health supplements if you're weighing options.
The buying mistake we see most: treating a topper like a fix
The most common error is adding a milk or broth topper on top of a food that isn't working, instead of addressing the food. A topper can't correct an unsuitable protein source, a fat content that's too high for a pancreatitis-prone dog, or a life-stage formulation mismatch.
When a customer comes in describing chronic loose stool or a dog that's stopped eating a food it used to like, we start with the bag, not the fridge. What's the kcal per cup? Has the formula changed? Is the dog getting 22% protein puppy food at age nine? Once the base diet fits, a kefir or broth is a genuine improvement ā better hydration, more enthusiasm at mealtime, a vehicle for supplements. Used the other way around, it just adds 20 to 100 kcal a day to a problem that's still there. The American Veterinary Medical Association is clear that persistent digestive changes warrant a clinical workup rather than dietary guesswork.
Our store at 1111A Finch Ave W, Unit 2, North York, ON M3J 2P7 is open 7 AM to 11 PM daily, with local delivery available via DoorDash and other apps. Bring in your current food bag and we'll read the guaranteed analysis with you before you add anything on top.
Bottom line: At $8.81 from $14.46, the Crosswind Farms 1 litre goat milk kefir is a solid buy at roughly 27 cents per 30 mL serving ā but only if your household finishes a litre inside the label's fridge window. Single cats and small dogs get better value from powdered goat's milk or a shelf-stable broth. Sale prices change, so confirm the current figure on the product page.

Questions we get about goat milk kefir
How much goat milk kefir can I give my dog per day?
A common starting guideline is about 30 mL (1 oz) per 10 lbs of body weight daily, capped so the topper stays under 10% of total calories. A 10 lb dog would get roughly 30 mL, a 30 lb dog around 90 mL, and a 60 lb dog up to about 120 mL. Introduce it over four to five days, and follow the product label if it differs.
Is goat milk kefir safe for cats?
Many cats tolerate fermented goat milk in small amounts because kefir cultures reduce the lactose already present at around 4.1%, but portion control matters far more for cats than dogs. Start with a teaspoon. A 10 lb cat's entire daily treat allowance is only about 20 kcal, which one 30 mL pour nearly uses up. Cats needing more moisture usually do better on wet cat food as a base diet rather than a dairy topper.
Does kefir replace a probiotic supplement?
No. Fermented dairy contains live cultures, but the label rarely states which strains or how many CFU per serving, so you can't dose it. If a veterinarian has recommended probiotics for a specific issue, use a supplement that prints strains and CFU counts. Kefir is better understood as a palatable, moisture-rich food topper that happens to be fermented.
Where can I find other current pet deals?
Discounted stock rotates weekly across the clearance sale and cat deals collections, and our price match guarantee covers items you find cheaper elsewhere. We also review markdowns as they land ā recent write-ups include the Honest Kitchen Goat's Milk N' Cookies deal at 45% off and the Kettle Craft venison and apple small-bite review. For quick answers on stock and ordering, see the pet store FAQ.
One last note on handling. If your bottle is labelled raw or unpasteurized, treat it like any raw product: separate utensils, clean surfaces, and refrigerate promptly. The FDA Center for Veterinary Medicine publishes handling guidance for raw pet foods that applies equally to raw dairy, and immunocompromised people in the household should skip handling it altogether. Beyond that, it's a simple product ā pour, watch, adjust.
