Taily Liquid Collagen is a genuinely well-made, single-focus skin-and-coat supplement, and it is also one of the more expensive dog collagens, with no joint-specific collagen in the bottle. Its label is disclosed to the milligram, it is third-party tested with a published certificate of analysis, and dogs tend to love the bacon flavor. What it does not include is undenatured Type II collagen (UC-II) or omega-3, the two ingredients with the best joint evidence. This review breaks down Taily’s real formula, price, and testing, then compares it fairly with a dual-collagen alternative.

What Taily Collagen is
Taily Liquid Collagen is a bacon-flavored liquid you drizzle over food once a day. It is built around hydrolyzed grass-fed collagen peptides with a short, sensible supporting cast, and it is positioned squarely for skin, coat, and shedding, with joint support described as a secondary, gradual benefit. It is made in the USA in a human-grade cGMP facility, and Taily publishes a full lot-specific certificate of analysis on the product page.
The verified label (per 1 mL)
| Ingredient | Amount per 1 mL | Role |
|---|---|---|
| Grass-fed collagen peptides (hydrolyzed) | 400 mg | Skin, coat, connective tissue |
| Vitamin C (ascorbic acid) | 20 mg | Antioxidant, collagen synthesis |
| Biotin (Vitamin B7) | 1.5 mg | Coat strength, less shedding |
| Hyaluronic acid | 1.0 mg | Skin hydration, joint cushioning |
| Inactive ingredients | 100 mg | Base and bacon flavor |
Dosing is by weight: 1 mL for dogs under 25 lbs, 2 mL for 25–50 lbs, and 3 mL for 50+ lbs. So a medium dog on 2 mL gets 800 mg of collagen, 3 mg of biotin, 2 mg of hyaluronic acid, and 40 mg of vitamin C per day. The 4 fl oz bottle lists at $39.99 and lasts a medium dog roughly 45 days.
What Taily does well
- Real transparency. Taily prints every active in milligrams and publishes a third-party certificate of analysis (Lot A2015) showing measured protein, biotin, hyaluronic acid, and vitamin C against label claims, plus clean microbiology. That is more than many pet brands show, and it deserves credit.
- Strong skin-and-coat stack. At a medium-dog dose it delivers more raw hydrolyzed collagen (800 mg) and more biotin (3 mg) than most competitors. If shedding and coat quality are your only concerns, this is a legitimately good formula.
- Palatability. The bacon flavor means most dogs take it without a fuss, which matters for daily compliance.
- Sensible extras. Vitamin C and hyaluronic acid are reasonable, evidence-aligned additions for a skin-and-coat product.
- Guarantee. A 60-day money-back guarantee lowers the risk of trying it.
Where Taily falls short
- No UC-II. Taily contains only hydrolyzed collagen. The form with the strongest canine joint evidence, undenatured Type II collagen, is not in the bottle. For a dog whose main issue is stiffness or mobility, that is a real gap.
- No omega-3. There is no fish oil or EPA/DHA, arguably the best-supported joint nutrient overall, so the “joint support” positioning leans mostly on hyaluronic acid.
- Price. At $39.99 per 4 fl oz bottle, it is among the priciest dog collagens, and larger dogs need 3 mL a day, which burns through a bottle faster.
- Flavor caveat. Bacon flavoring drives acceptance, but a minority of owners report loose stool or vomiting when starting, particularly in small dogs. Introduce gradually.
Taily vs Pure Majesty Liquid Collagen
The closest head-to-head is another once-daily liquid, Pure Majesty Liquid Collagen. Both are disclosed, both are batch-tested, and both skip xylitol and fillers. The difference is philosophy: Taily concentrates on hydrolyzed collagen for skin and coat, while Pure Majesty spreads across two collagen forms plus joint and gut actives.
| Factor | Taily Liquid Collagen | Pure Majesty Liquid Collagen |
|---|---|---|
| Format & dose | Liquid, 1–3 mL by weight | Liquid, flat 2 mL for all dogs |
| Hydrolyzed collagen | 400 mg/mL (800 mg at 2 mL) | 462 mg Type I & III |
| UC-II (Type II) | None | 48 mg (clinical dose range) |
| Omega-3 (EPA/DHA) | None | ~126 mg salmon oil |
| Hyaluronic acid | 2 mg at 2 mL | ~8.4 mg |
| Biotin | 3 mg at 2 mL | None |
| Other actives | Vitamin C 40 mg at 2 mL | MSM ~63 mg, S. boulardii postbiotic ~21 mg, L-glutamine ~52 mg, bone broth, ginger, astaxanthin |
| Third-party testing | Published lot COA on page | COA on every batch |
| List price | $39.99 (4 fl oz) | $23.99 |
Read honestly, each wins something. Taily wins on raw skin-and-coat material: more hydrolyzed collagen at a medium dose, plus biotin and a big vitamin C dose that Pure Majesty doesn’t match. It also puts its full third-party COA front and center, which is a transparency point worth respecting.
Pure Majesty wins on breadth and joints: it is the one carrying UC-II at 48 mg (in the range used in the dog trials) and micro-emulsified omega-3, the two ingredients that actually move joint outcomes, plus more hyaluronic acid, MSM, and a postbiotic, at a lower bottle price. If you want a single product for coat and mobility, it covers more ground for less money. You can compare the current formula on the Liquid Collagen product page.
⭐ Our pick for coat + joints in one: Pure Majesty Liquid Collagen for Dogs ($23.99) pairs hydrolyzed Type I & III with clinical-dose UC-II and omega-3 in a measured 2 mL dose. See the label and price. A daily wellness supplement, not a medication.
What about Healthy Petz and other liquid collagens?
Taily is not the only bacon-or-broth-flavored liquid collagen on the market; brands such as Healthy Petz compete in the same space. The buying rule is the same for all of them: check whether the label discloses milligrams per serving, whether it includes UC-II or only hydrolyzed peptides, and whether omega-3 is in the mix. If you want the background on collagen types before you shop, start with our collagen for dogs guide, then use our best collagen for dogs comparison for the full field.
Who should buy Taily, and who shouldn’t
Consider Taily if your dog’s issue is strictly skin, coat, and shedding, your dog is small (so the by-weight dosing keeps cost reasonable), and you want a product with a published third-party COA and a palatable flavor.
Look elsewhere if your dog needs joint or mobility support, you want omega-3 included, or price per day matters and you have a large dog. In those cases a dual-collagen liquid with UC-II, or a dedicated joint product from our best joint supplement for dogs guide, is the better spend. If you would rather give a chew than a liquid, our collagen sticks guide explains what chews can and can’t do.
When to see your vet
Collagen is a supplement, not a treatment. If your dog is limping, itching intensely, losing hair in patches, or has skin that is red, greasy, or smelly, see your vet, those signs point to conditions that need diagnosis. Check with your vet before starting any supplement if your dog is on medication or has a chronic illness.
Frequently asked questions
Is Taily collagen good for dogs?
Yes, for skin and coat it is a solid, transparent product with a strong hydrolyzed-collagen and biotin dose and a published certificate of analysis. Its main limitations are the higher price and the absence of UC-II and omega-3 for joints.
How much collagen is in Taily?
Taily contains 400 mg of hydrolyzed collagen peptides per mL, so a medium dog on the 2 mL dose gets 800 mg per day, along with 3 mg of biotin, 2 mg of hyaluronic acid, and 40 mg of vitamin C.
Does Taily collagen help with joints?
Only modestly. It provides hyaluronic acid but no UC-II and no omega-3, the ingredients with the strongest joint evidence in dogs. For mobility, a product that includes UC-II is a better match.
How much does Taily cost?
The 4 fl oz bottle lists at $39.99 (subscription pricing is lower), which lasts a medium dog about 45 days. That makes it one of the pricier liquid collagens, especially for large dogs that need 3 mL daily.
Is Taily collagen safe?
It is made in a human-grade cGMP facility, third-party tested, and free of xylitol, wheat, soy, and artificial colors. A few owners report mild digestive upset when starting, so introduce it gradually and check with your vet if your dog has allergies or takes medication.
