Is your dog or cat a rescue? Unhealthy? Losing weight?

Trust Miracle Vet to add healthy weight to your dog & cat fast.

Miracle Vet is the only liquid weight gainer for dogs & cats that’s as healthy as it is effective. Unlike our competitors, who pack their products full of cheap ingredients and empty calories, we make sure Miracle Vet is packed with good-for-them vitamins, nutrients, and more.

It’s the healthy weight gainer for owners who truly care about their dogs & cats.

7-in-1 Formula

The 29 vitamins & minerals in our veterinarian-approved formula deliver all these benefits to underweight and malnourished dogs & cats:

  • 1.) Gains weight quickly & healthfully
  • 2.) Improves skin & coat health while decreasing shedding
  • 3.) Increases energy, appetite, & stamina
  • 4.) Improves your dog’s & cat's immune system
  • 5.) Decreases joint problems & inflammation
  • 6.) Reduces heart attack & stroke risk
  • 7.) Fuels exercise performance & recovery

Nutrient-Dense Calories

As a weight-gaining supplement for dogs & cats, Miracle Vet is packed with calories to help your pet gain weight quickly & easily. Every 16-oz bottle contains 2,400 high-quality calories.
But anytime a pet is underweight, they need more than simply calories to grow. An underweight dog or cat is a malnourished pet, which means their body is in desperate need of vitamins and minerals.

And that’s why we fortify Miracle Vet with all the critical nutrients your pet needs to grow and reach a healthy weight, including:

  • Vitamin A
  • Vitamin D3
  • Vitamin E
  • Biotin
  • Folic Acid
  • Niacin
  • Pantothenic Acid
  • Vitamin B1
  • Vitamin B2
  • Vitamin B6
  • Vitamin B12
  • Vitamin C
  • Vitamin K1
  • Copper
  • Iodine
  • Iron
  • Manganese
  • Selenium
  • Zinc
  • Choline
  • Calcium
  • Taurine
  • Lecithin


    As a side benefit of acquiring all these nutrients, your pet will also reap the rewards of better health, more consistent energy levels, and a stronger immune system!

    Whey Protein + Fish Oil: A Perfect Combination

    The #1 ingredient in this product is fish oil, the heart- and brain-healthy fat that’s great for skin & hair. It’s no wonder why Miracle Vet also works miracles for your pet's skin & coat!
    And the protein we use in Miracle Vet is the highest quality available anywhere. With a biological value rating of 159, whey protein isolate contains all the essential amino acids and is easily digested & absorbed. It’s the same type of protein supplement used by professional athletes around the world.

    NO Harmful Ingredients

    Because we want your pet to live a long, healthy life, we NEVER use cheap harmful ingredients:

    • NO trans fats
    • NO cheap soybean oil
    • NO artificial colors
    • NO artificial flavors
    • NO glycerin
    • NO propylene glycol
    • NO artificial glycerin
    • NO tartrazine (FD&C yellow #5)

    If every manufacturer of pet food & pet supplements could say the same thing, then the world would have a lot more healthy pets.

    Quick & Easy to Use

    It’s hard to imagine a supplement being easier to use than Miracle Vet.

    Simply add a few drops to your pet's food or water, and you’re done!

    There’s no shaking, no mixing, no stirring—and no hassle.
    You can even feed it directly to your pet using a syringe if you prefer. Dogs & cats love the natural vanilla flavor.
