My vet said Benny's stiffness was just age. He's 11. Started Avellin figuring I had nothing to lose. Three weeks in, he got up without that awful pause. This morning he followed me to the kitchen for the first time in months. My boy is still in there.
90-Day Money Back Guarantee
If your dog doesn't show a visible difference, send the bottle back. Full refund. No questions, no hassle. We can offer that because we've watched this work for thousands of dogs, and we're betting it works for yours too.
The Science Behind It
+
Most hip and joint supplements for dogs fail at one thing: delivery. Hard chews and powders rely on your dog's digestion to break down the actives, and most of it never reaches the joints.
That's why Avellin uses a cold-pressed liquid format with hydrolyzed collagen Types I, II, and III, paired with hyaluronic acid and glucosamine HCl. The peptides are pre-broken down and dispersed in liquid, so they bypass digestion and absorb directly. Up to 99% bioavailability vs. as little asxq 30% from chews.
Every drop delivers a clinical-grade dose of what aging joints actually need to rebuild cartilage and reduce stiffness at the source.
Ingredients
+
Every ingredient in Avellin is there for a reason. Delivered in acold-pressed liquidyour dog can actually absorb, not lose to digestion. We don't hide behind heat-processed chews, fillers, or vague "joint complexes." You get a transparent list of clinically supported ingredients, each dosed at a meaningful level and built to reach your dog's joints.
- Collagen Peptides: 400mg, Types I, II & III
- Glucosamine HCl: 20mg, Joint cushion & lubrication

Yes. Avellin is made with all-natural ingredients in a GMP-certified facility and is third-party lab tested for purity and potency. No artificial fillers, no synthetic preservatives, no fluff.
Collagen, glucosamine, and hyaluronic acid are well-tolerated by dogs of all sizes and breeds. However, if your dog is pregnant, nursing, or on prescription medication, we recommend consulting your veterinarian before starting any new supplement, just to be safe.

What Sets Our Collagen Apart
Most dog joint supplements sound the same. But there are critical differences in how they're made, dosed, and delivered that decide whether your dog actually feels the result. Here's why ours stands out:
Cold-Pressed Liquid for Real Absorption
Most chews, tablets, and powders lose potency in your dog’s gut. Avellin's cold-pressed liquid keeps peptides intact and pre-dispersed, helping up to 98% of the active material reach the joints versus as little as 12% from a standard chew.
5 Joint-Targeted Actives, Not a "Proprietary Blend"
Every dose delivers 400mg of Collagen Peptides (Types I, II & III), 20mg of Glucosamine HCl, and Hyaluronic Acid to support cartilage, connective tissue, cushioning, and joint fluid. Cold-pressed and sourced from pasture-raised, grass-fed bovine with no fillers or mystery blends.
Easy to Give, Even to Picky Dogs
Even the best supplement is useless if your dog won’t take it. Avellin's liquid mixes into food unnoticed—no chewing, no battles, and no wasted product, even for picky dogs.

Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
What makes this collagen supplement different?
+
Unlike most brands that use hard chews and powders that lose material to digestion, we use a cold-pressed liquid format with collagen types I, II, and III plus hyaluronic acid. No fillers, no hard chews, just usable peptides your dog will actually take.
Does collagen really help with hip and joint issues in dogs?
+
Yes. Type II collagen is a key building block of cartilage, and hyaluronic acid is a natural part of joint fluid. Together they support how joints cushion and move, and most pet parents see mobility wins within weeks of daily use.
Why does this come in liquid form?
+
Hard chews lose material to heat processing, fillers, and digestion before any of it reaches the joint. Liquid micro-peptides come pre-dispersed, so your dog's body absorbs more of what's on the label with less waste.
How long until I see results?
+
Most pet parents report noticeable mobility improvements within 2 to 4 weeks of daily use, especially with rising, stairs, and overall energy. Some dogs respond sooner, but consistent daily use is essential.
What's the correct dose and how should I give it?
+
Follow the label, the daily amount depends on your dog's weight. Pour it over your dog's food once a day. Most dogs eat it like any other meal, no wrestling and no hidden pills.
Are there any side effects?
+
Collagen is safe for most dogs. A few may experience mild stomach upset, which can usually be avoided by giving it with food. Always follow the directions on the label.
Is it safe to give with medications?
+
If your dog is on blood thinners, anti-inflammatories, or has existing health concerns, speak with your vet before starting Avellin. It may interact with certain medications.
How is this better than regular joint chews?
+
Most joint chews lose a large portion of their active material to heat processing, fillers, and digestion. Our liquid format is cold-pressed to preserve peptides and delivers collagen plus hyaluronic acid in a form your dog's body can actually use.
