10 Best Vitamin Gels For 12 Week Puppy in 2026

A 0.3-pound tube of chicken-flavored gel that packs extra calories without adding another meal, that’s the straightforward promise of this supplement. It’s formulated for puppies eight weeks and older, which puts it right in the window for a young pup who might be lagging on weight or just needs a boost between meals. The energy-rich vegetable fats are designed to be easy on a young digestive system, so you’re less likely to deal with upset stomachs while trying to get those calories in. For a puppy that’s growing fast, recovering from illness, or simply a picky eater, this gives you a simple tool to bridge the gap without guesswork.

The trade-off is that this gel focuses purely on calories and digestibility, it doesn’t bring a multivitamin or mineral blend to the table, unlike the PetAg Vitamin and Mineral Supplement Gel. That means if your puppy needs broader nutritional support, you’d be layering products. But for a straightforward, no-fuss calorie boost that’s easy to feed and gentle on the gut, this gel does exactly what it says. It’s a targeted solution for a specific problem, and for that reason it earns the top spot in this guide.

A 0.2-pound tube of chicken-flavored gel that delivers vitamins and minerals specifically for puppies means this supplement is designed around the nutritional needs of a growing dog, not just a generic adult formula. That targeted formulation is what earns it the Best Puppy Multivitamin Gel spot in this guide. For a puppy whose body is building bone, muscle, and immune defenses at a rapid clip, having a supplement that matches those developmental stages matters more than a one-size-fits-all vitamin. The gel format also makes it easy to sneak into a meal or offer straight from the tube, which helps when your puppy is still figuring out whether that bowl of kibble is friend or foe.

The real trade-off here is that this gel focuses on vitamins and minerals, not calories. If your puppy is underweight, a picky eater, or recovering from illness, you would be better off with the PetAg High Calorie Gel Supplement. That product delivers extra calories and is labeled for dogs eight weeks and older. It is also heavier at 0.3 pounds. But for a healthy puppy that needs a nutritional top-up without added calories, this gel fits the bill without overcomplicating things.

A 5ml single-serve gel packet means you get exactly the right dose for a small puppy without guessing, measuring, or cleaning up sticky spoons. That precision matters when you’re raising a small breed whose nutritional needs change fast, and Mervue packs in beta-glucans, Vitamin C, and Vitamin E to support natural defenses during the early months. The addition of L-Carnitine and B-vitamins helps maintain energy without overloading a tiny system, while Omega-6, Biotin, and Zinc target coat quality from the inside. For owners of small breeds who want a straightforward, mess-free way to cover daily vitamins, this gel hits the mark without the fuss of powders or liquid bottles.

This gel is engineered for dogs under 25 pounds, so if your puppy is a larger breed that will outgrow that weight in weeks, you’ll need to switch products sooner than you might like. Compared to the PetAg Vitamin and Mineral Supplement Gel, which comes in a 3-1/2-ounce tube and works for puppies of any size, Mervue’s single-serve packets offer better freshness control but less flexibility for growing dogs. It also doesn’t provide extra calories for underweight pups the way a high-calorie gel like Tomlyn Nutri-Cal does. So if your puppy needs weight gain support alongside vitamins, you’ll want to pair it with something else.

With a 2.2-pound bottle packed with salmon oil, probiotics, and a full lineup of vitamins A, D3, E, and B-complex, this gel is built for puppies who need more than a light nutritional boost. It targets underweight or recovering pups specifically, offering high-calorie support alongside digestive aids that help those extra nutrients actually get absorbed. That makes it a strong fit for a puppy who’s lagging behind on weight or struggling to keep food down, especially since it’s labeled safe from 8 weeks onward.

The bottle size is the main consideration here. At over two pounds, it’s noticeably heavier than other gels in this guide, which might matter if you’re traveling or need something easy to squeeze one-handed while wrangling a squirmy pup. Compared to the PetAg High Calorie Gel at 0.3 pounds, this one commits to a bigger supply but less portability. If your puppy just needs a gentle vitamin top-off rather than serious weight gain support, a lighter option like the PetAg gel might suit you better. For a pup that genuinely needs to pack on pounds, though, this formula covers more ground.

The malt flavor and smooth gel texture mean you can squeeze it directly onto your puppy’s nose or paw, and they’ll lick it off without a fight. That design makes this a strong option for a puppy who turns up their nose at regular food or supplements. It delivers omega-3, 6, and 9 fatty acids from fish oil to support joint, heart, and skin health during that rapid growth phase. So you’re not just getting calories, you’re getting targeted nutrition in a form the puppy actually wants to eat.

Malt flavor isn’t universal. Some puppies love it; others give you that flat look of betrayal. If your pup is the latter, you’ll be wiping gel off your floor more than you’d like. Unlike the PetAg High Calorie Gel Supplement, which uses chicken flavor, this one leans into sweetness rather than savory. For a puppy who already eats well and just needs a vitamin boost, the chicken option might be less polarizing. But for the truly picky eater who needs calories and won’t touch a bowl, the malt delivery system here is hard to beat.

The 2-in-1 colostrum-and-calorie formula combines immunoglobulins and growth factors from bovine colostrum with a high-calorie base to support immune function and weight gain in dogs and cats. The chicken flavor is designed to encourage eating in older pets, and the gel requires no refrigeration after opening, so it can be stored in a cupboard. For a pet that needs both immune support and extra calories, such as a senior with appetite loss or a young animal recovering from fatigue, this gel addresses both needs in one product.

The concentrated colostrum protein in this gel demands a gradual introduction: start with one-third of the suggested amount, then increase slowly while monitoring tolerance. That means you can’t just squeeze it into a bowl on day one, you need to follow a short acclimation schedule. For a healthy pet that just needs extra calories without that step, the PetAg High Calorie Gel is a simpler option, as its product description doesn’t mention any multi-day introduction requirement.

A dual-source omega-3 formula from krill oil and flaxseed means this gel delivers EPA, DHA, and ALA in one squeeze, supporting a healthy skin barrier and a soft shiny coat for dogs and cats. With 22 active ingredients including quercetin and astragalus root, it supports normal histamine levels and a balanced immune response alongside everyday vitamins and minerals, a pairing rarely found in a daily multivitamin. That makes it a strong pick for owners who want broad coverage without stacking multiple supplements, especially if their pet is a picky eater who leaves chews in the bowl.

Krill oil means this gel isn’t suitable for pets with a shellfish allergy, so check with your vet first. You’ll need to start with half a serving for the first 5-7 days to let your pet’s stomach adjust, then move to the full dose. If your pet tolerates shellfish and you want an all-in-one immune, skin, and digestive support, this covers more ground than a basic vitamin gel.

Omega-3, -6, and -9 essential fatty acids from fish oil support joint, heart, and skin health during a puppy’s rapid growth phase. That makes this gel a practical option for a young dog who needs extra calories but also benefits from those fatty acids for developing joints and a healthy coat. The malt flavor and smooth texture let you squeeze it directly onto a paw or nose, which helps when a pup is too busy exploring to eat a full meal.

The tube size is the main drawback here: at 4.25 oz, it’s smaller than the 5 oz PetAg High Calorie Gel Supplement, so you may need to buy a second tube sooner if your puppy is a heavy eater or needs sustained calorie support. But for the budget-minded owner who wants a straightforward, no-fuss gel with solid nutritional basics, this one delivers the essentials without extra ingredients that drive up cost.

A 3.5-ounce tube of salmon-flavored gel that was formulated by veterinarians means this isn’t just another calorie booster, it’s a targeted supplement for dogs who need extra energy and weight gain support. The inclusion of Omega-3 and Omega-6 fatty acids goes beyond simple calories, supporting brain function and coat health. If your dog is recovering from illness, struggling with appetite, or just needs a nutritional lift, this gel delivers vet-designed coverage in a format you can squeeze onto food or straight into their mouth.

Portion size is the main trade-off: at 3.5 ounces, this tube is smaller than the 5-ounce PetAg High Calorie Gel, so if your dog needs daily supplementation over several weeks, you may need to reorder sooner. That said, the vet-formulated blend and salmon flavor give it an edge for picky eaters who might turn their nose at chicken or malt alternatives. For a short-term recovery or appetite jumpstart, the targeted nutrition here is worth the extra trip to the store.

The dosage is straightforward, 1½ teaspoons per 10 pounds of body weight daily, and can be doubled if your pup is refusing food or needs extra recovery support. This suits owners who want a single gel that covers both energy and essential fat-soluble nutrients without juggling multiple bottles.

The malt flavor is palatable to most pets, but some may prefer something else. Unlike the PetAg High Calorie Gel Supplement, which uses chicken flavor, Vetri-CAL offers a different taste that not every pet will accept. If your dog or cat does take to malt, the Omega 3-6-9 blend provides fatty acids that support skin and coat health as listed in the product’s nutrient profile.
