Most joint supplements support just one part of the joint. Coastline supports the whole joint for more long-term mobility support and more good years together.
You have 90 days from the day your order is delivered, and the guarantee covers both taste and results. If Coastline is not the right fit for your dog, contact us using the support details sent with your order and we will help you through the refund.
Many owners notice changes within 2 to 4 weeks with consistent daily use. Some dogs take a little longer, which is why every order is backed by our 90-day money-back guarantee.
If you are worried about it, feel free to reach out to your veterinarian. If your dog takes medication or another supplement, we recommend consulting your veterinarian before use just to be safe.
Real dogs, moving easier. Here's what changed once they started Coastline.
Most joint supplements focus on one or two areas. Coastline supports all four: cartilage, lubrication, connective tissue, and the body’s normal inflammatory response.
Formulated around published research on glucosamine, chondroitin, MSM, Green Lipped Mussel, Boswellia, and turmeric for joint health.
Most joint supplements focus on one or two areas. Coastline supports all four.
Every ingredient listed by name. No proprietary blend.
No stacking five bottles on the counter. All four chambers are already in the one chew made specifically for your dog and their long term mobility.
In the early 1970s, researchers noticed something unusual: coastal Māori communities in New Zealand had markedly lower rates of arthritis than inland populations. The dietary difference was raw green lipped mussel, eaten daily as a staple food.
The Green Lipped Mussel is endemic to New Zealand and cannot be farmed or replicated anywhere else. It grows in the Marlborough Sounds, fed by nutrient rich, cold coastal currents.
Green Lipped Mussel contains ETA, a rare omega 3 found in few other marine sources. It is one of the ingredients feeding Chamber 2, not a stand alone cure all.
Dosed by weight, given straight from your hand or dropped in their bowl. No mixing, no powder residue left behind.
The Four Chamber Stack that's formulated in every chew builds up in your dog's system over 2 to 4 weeks. Skipping days during the first month slows how quickly you'll see a difference.
No stacking five bottles on the counter. All four chambers are already in the one chew made specifically for your dog and their long term mobility.
A side by side look at what single ingredient formulas leave out.
| Coastline | Single Ingredient Formulas |
|---|---|
| Feeds Chamber 1 (cartilage), glucosamine + chondroitin | Most feed this chamber only |
| Feeds Chamber 2 (lubrication). MSM + NZ Green Lipped Mussel | Rarely addressed at all |
| Feeds Chamber 3 (connective tissue). Boswellia + sulfur | Almost never included |
| Feeds Chamber 4 (inflammation), turmeric + omega 3 | Left out of most formulas |
| Bacon liver chew even picky dogs eat | Powders and tablets, often refused |
| Supports smoother everyday movement, from getting up to stairs, walks, and play | Single-focus formulas can leave parts of the joint routine unsupported |
A lot of joint products focus on one or two parts of the joint, while Coastline is built to support the whole joint routine, cartilage, lubrication, connective tissue, and a healthy inflammatory response. Every ingredient is there for a reason, so this is meant to be one simple daily routine you can actually stick with.
We understand that some dogs are picky, which is exactly why the 90-day guarantee covers taste too. Give Coastline a fair try, and if your dog will not eat it, contact us and we will help you through the refund.
Osteoarthritis can already be present in young dogs, including dogs under 4, even before owners notice obvious slowing down. That is why many dog parents choose to start joint support early rather than waiting for everyday movement to change.
Many owners notice changes within 2 to 4 weeks with consistent daily use. Some dogs take longer, which is why we give you 90 days to see how Coastline fits into their routine.
Most dogs tolerate joint supplements well when used as directed, but every dog is different. Introduce Coastline gradually, follow the serving by weight, and consult your veterinarian before use if your dog has a medical condition or takes medication.
Dogs 10 lbs and under get 1 chew, 11 to 39 lbs get 2, 40 to 79 lbs get 3, and 80 lbs and over get 4 chews per day. Daily consistency matters more than giving extra.
Most regular joint chews are built around one familiar ingredient or one part of the joint. Coastline combines 12 targeted ingredients around a four-part joint-support framework in one daily chew.
If your dog has a medical condition or takes medication, consult your veterinarian before use. We would rather you feel completely comfortable with what your dog is taking than guess.
“Luna stopped putting weight on one back leg and after all the vet bills I still felt like something was off. Found Coastline on Facebook and thought, we already spent this much... might as well try it. We stayed consistent. A few weeks later the crouching wasnt happening as much. Wasnt overnight, but for me it was worth waiting. I just dont worry every time I watch her walk now.”
“Tucker doesnt have obvious joint issues yet. Thats actually why I started. I kept reading what other owners went through and honestly it scared me a little. Ive had him since he was a pup and I want to keep him moving like Tucker for as long as I can. He thinks its a treat, its easy, so we just keep it in the routine.”
“Jackson knows when somethings a supplement lol. He’d sniff the other chews and spit them right back out. Powders were worse. So I was skeptical with these too. First time I opened the tub he actually wanted one. Now he hears it open and comes over. Thats honestly half the battle for me.”
“Diesel started limping young and I kept hearing he probably pulled something. I didnt even know dogs could get arthritis like people do. I started Coastline mostly because I wanted to do something. It wasnt a week-one thing, but over time he just looked more like himself. We havent even finished the first tub and I already ordered 2 more lol.”
“Maggie is 11 and the stairs were getting rough. She’d stop at the bottom and just look at me. Almost a month in she started getting on the couch by herself again. Still needs help sometimes, but yeah... that was a big deal for us.”
“Winston had been limping after play for probably 2 years. Vet kept saying rest, so thats what we did. I saw Coastline and figured why not, especially with the guarantee. It took some time but he’s running around the yard again. Honestly didnt think I’d see that.”
“I have two shepherds and Rex is the bigger one. His hips were just starting to show his age. About 6 weeks in he seems to move easier, especially in the mornings. Nothing crazy overnight. I can just tell when we miss his chew, and he LOVES getting it.”
“Buddy is picky with anything that smells like a supplement. Chews, powders, didnt matter, he’d walk away. These are the first ones he actually waits for. I dont know if its the taste or what lol, but I’ll take it.”
“I wasnt expecting some overnight miracle and thats pretty much how it went. A few weeks in Zoe wasnt hesitating as much before getting up. Little by little she just looked more like herself again. At her age thats really all I wanted, more good time with my girl.”
“Biscuit is only 4 so he doesnt really have joint problems yet. My last dog was fine too... until one day he wasnt. So this time I wanted to start earlier. Biscuit thinks these are treats anyway. I put one by his bowl and sometimes toss it to him to catch. Easy enough.”
