Picky Eater? How to Give Your Dog a Liquid Supplement
Mix the 2 mL into something wet and tasty: a spoon of wet food, or kibble softened with warm water. Measure away from the bowl, keep the dropper off the food, and give it at the same meal daily. Never squirt oil into the throat. If your dog still refuses Mighty K9, the sales FAQ says the 30-day guarantee covers it.

Why it happens
Why do some dogs refuse a liquid supplement?
Most refusals come from smell, texture or surprise. A dog that eats the same kibble every day notices anything new on top, even bacon-flavored oil.
Mighty K9 is mostly olive oil with ESS60 and bacon flavor, 2 mL once a day in food. Oil sits on dry kibble as a slick, shiny layer. Some dogs lick around it. Others sniff, walk away and come back later. Small dogs and seniors with a dull sense of smell can be the fussiest. The fix is usually how you serve it, not the dog.
Step by step
How do you give a liquid supplement to a picky dog?
Hide it in something wet and mix it through the whole meal. The product page says to measure 2 mL, drizzle it over the meal and mix it into food.
- 01
Measure away from the bowl
Draw 2 mL, which is 2 full droppers by the brand's count. Do it at the counter, out of your dog's sight.
- 02
Drizzle on something wet
Drip it over a spoon of wet food, or over kibble softened with a splash of warm water.
- 03
Mix it in well
Stir until the oil coats every piece. A dog cannot pick around oil that is spread through the whole meal.
- 04
Same meal, every day
Use the same meal for 30 days. Routine helps fussy dogs, and one bottle holds 30 servings.
What to mix it with
Which foods hide a liquid supplement best?
Wet, smelly foods hide oil best. The sales FAQ says it mixes into kibble, wet food or broth. Use what your dog already eats so you add few calories.
| Method | How | Good for | Watch for |
|---|---|---|---|
| Wet food spoon | Mix into one spoon of the dog's usual wet food, serve first | Most picky dogs | Count the spoon in the day's food |
| Warm water on kibble | A splash of warm, not hot, water, then stir in the oil | Dry-food dogs | Serve soon; do not leave wet kibble out |
| Plain broth | A little low-salt broth with no onion or garlic | Seniors who like gravy | Read the broth label |
| Dry kibble only | Drizzle and toss well | Dogs who eat anything | Oil can pool at the bottom |
Clean habits
How do you keep the supplement dropper clean?
Keep the dropper away from food, mouths and counters. Saliva or food bits on the glass tip can end up back in the bottle.
- Hold the tip a little above the food. Do not touch it to the bowl or kibble.
- Never let your dog lick the dropper.
- Wipe the outside with a clean, dry paper towel if oil runs down.
- Put the dropper straight back and close the cap. The label says to store it in a cool and dark place.

Mistakes to avoid
Can you put a liquid supplement straight into a dog's mouth?
Do not squirt oil into the back of your dog's mouth or throat with a dropper or syringe. Oil given that way can go down the wrong pipe. The product directions say to mix it into food, so stick with that.
The sales FAQ says once daily in food. Splitting 2 mL into two smaller bites, morning and evening, is not on the label. Do it only if your vet agrees.
Also skip extra oil, butter or bacon grease to tempt your dog. Fats and oils can cause vomiting and diarrhea, and potentially pancreatitis in some pets (ASPCA, People foods). For the full list, see side effects and cautions.
Timing
What is the best time of day to give a picky dog its supplement?
Give it at the meal your dog eats most eagerly. For many dogs that is breakfast, when they are hungriest.
- Breakfast, about 7:30
Drizzle 2 mL over the meal and mix. The sales FAQ says once daily in food; the same meal each day is easiest to remember.
- Or with dinner
If mornings are rushed, dinner works just as well. Pick one meal and stick to it.
- Walks
Short, regular walks on soft ground suit stiff seniors better than one long weekend outing.
- Rest
A padded bed off cold floors helps an older dog rise more easily. Watch how the first steps of the morning look.
Timing is a suggestion: the label and sales FAQ say only "once daily" in food. Weight and activity matter most for joints (ACVS, Osteoarthritis).
When to worry
When is a dog refusing food a sign of a health problem?
When your dog refuses its normal meal too, not just the new topping. Turning down one new taste is normal. Turning down food it loves is not.
Picky, but fine
Eats the usual meal without the oil, drinks normally, plays and moves as always.
Possible illness
Skips meals for more than a day, vomits, has diarrhea, drools, paws at the mouth or seems tired.
Mouth pain from a bad tooth can look like fussiness in older dogs. Vomiting, belly pain and diarrhea can be signs of pancreatitis, which needs a vet (Merck Vet Manual, Pancreatitis). Stop the supplement and call your vet if you see any of these.

FAQ
Picky eater supplement FAQ
How do I get my picky dog to take liquid supplements?
Mix the liquid into a spoon of wet food or kibble softened with warm water, and stir it through the whole meal. Measure out of sight, give it at the meal your dog likes best, and keep the routine the same each day. Most dogs accept it within a few days.
Can I drop Mighty K9 straight into my dog's mouth?
No. The product directions say to drizzle 2 mL over the meal and mix it into food. Squirting oil into the back of a dog's mouth or throat with a dropper or syringe can make it go down the wrong way. Keep it in the food bowl.
Can I mix Mighty K9 with wet dog food?
Yes. The sales FAQ says it mixes into kibble, wet food or broth. Wet food hides the oil best for picky dogs. Stir 2 mL into a spoon of your dog's usual wet food and serve that first, then the rest of the meal.
Can I split the Mighty K9 serving between two meals?
Only if your vet agrees. The label serving is 2 mL once daily in food, and the sales FAQ says to keep it consistent. Splitting it into two smaller bites is not part of the brand's directions, so ask your vet before changing how you give it.
What if my dog won't eat Mighty K9?
Try wet food and the same meal for about a week. If your dog still refuses, the sales FAQ says a refused bottle can be returned under the 30-day money-back guarantee. Call +1 (302) 200-3480 with your order ID before day 30; return shipping is on you.
Why did my dog suddenly stop eating its food?
A dog that refuses its usual meal, not just a new topping, may be unwell. Dental pain, stomach upset and other illness can all cause it. If your dog skips meals for more than a day, vomits, has diarrhea or seems tired, stop any supplement and call your vet.
