Ask Ariel’s Ultra-Flex Collagen for dogs and cats is a natural, "whole-food" supplement that is tasteless and easy to administer. Just sprinkle on your pet’s food - one dose a day is all that is needed to give your cat or dog the benefits of collagen. The ingredients are backed by extensive research and clinical trials.
Collagen is a structural protein found in the bones, muscles, skin, tendons, and digestive tract of your pet. It is the "cellular glue" that holds the body together. Natural collagen production declines as your pet ages, which can lead to decreased elasticity and stability in the joints, muscles and connective tissue. Collagen supplements for dogs and cats can also be used to aid in recovery and repair of bones, tendons and ligaments in pets that have suffered injuries.
The key ingredient in Ultra-Flex Collagen for dogs and cats is NEM® brand eggshell membrane - a safe, all-natural whole-food source containing three varieties of collagen, glycosaminoglycans (GAGs) such as chondroitin sulfate, glucosamine, hyaluronic acid, and enzymes, which support joints and connective tissue. Ultra-Flex Collagen for dogs and cats contains key enzymes for enhanced absorption and bioavailability.
Yes, collagen is a natural protein and is generally well-tolerated by pets. Because Ultra-Flex contains NEM® eggshell membrane, pets with egg allergies should not use this product. If your pet is especially sensitive, starting with half the recommended dosage of collagen is the best way to start. Clinically tested NEM® eggshell membrane collagen is safe, natural and effective, helping pets maintain mobility, recover faster from injuries, and enjoy playtime again.*

Pets allergic to glucosamine
NEM® (Natural Eggshell Membrane) is a clinically tested, whole-food form of collagen for pets that provides natural joint and cartilage support. It contains collagen types I, V, and X, along with glucosamine, chondroitin, and hyaluronic acid—key nutrients that help maintain flexibility and comfort in dogs and cats.
Unlike many synthetic collagen sources, NEM® collagen is gently derived from eggshell membranes using an all-natural, patented process. The eggshells and membranes are carefully separated, partially hydrolyzed, and dry-blended to produce a 100% pure powder. Every batch of NEM® collagen is made in the USA in FDA-inspected, NSF-certified GMP facilities, and tested to ensure it’s free of heavy metals and bacteria.
This makes Ultra-Flex Collagen a safe, natural way to support your pet’s joints, cartilage, and connective tissue with clinically proven NEM® collagen.
"Our 7 year old Pudlepointer Ember suffered a devastating leg injury 2 years ago. She suffered a committed fracture which required multiple surgeries and plating if her leg. Her vet recommended several supplements and we even tried injections to reduce her pain and limping. I turned to Ask Ariel for advice and started Ember onUltra-Flex and ArthroStride. Within two weeks, she had completely stopped limping and was running like the wind! She was doing so well, when the supplements ran out, we didn't bother to refill. Fast forward a few months and the poor dog is limping again with no initiating incident. We put Ember back on ArthroStride and Ultra-Flex and it worked even faster this time! No more going off supplements, thank you for helping our dear, sweet Ember"
One of the hardest things to watch is your dog or cat slowing down—no longer running or playing like they used to because of arthritis or joint pain. Age, activity and past injuries can wear down your pet’s joints, ligaments and tendons over time. Collagen plays a vital role in your pet’s comfort and mobility— it’s the natural "glue" that gives joints their strength, flexibility and cushioning.
As pets age, their natural collagen levels decline, leading to stiffness, arthritis and a higher greater risk of injuries such as ACL tears, luxating patella and hip or elbow dysplasia. Adding collagen to their daily routine helps protect joint cartilage and strengthen connective tissue, making it more comfortable for them to walk, run and play.
Repairs and strengthens connective tissue
Strengthens cartilage over time
Helps prevent future joint and ligament damage
Reduces discomfort related to arthritis
Cartilage cushions bones and ligaments and is made of collagen, elastin, proteoglycans and glycosaminoglycans. Ultra-Flex Collagen provides these key nutrients naturally:
Collagen: Supports joints, cartilage, bones and connective tissue. Helps reduce inflammation.
Glycosaminoglycans (GAGs): Provide cushioning and joint lubrication.
Proteoglycans: Strengthen connective tissues and extracellular matrix.
Elastin: Gives tissues flexibility, supporting joints, spine and overall mobility.
Ultra-Flex Collagen isn’t just for older pets - it can benefit dogs and cats at every stage of life. Adding collagen early helps support healthy joint and cartilage development in growing or active pets, keeping them strong and resilient through all their adventures. For young, large-breed dogs prone to bone or joint issues like panosteitis (a painful inflammation of the long bones), collagen provides key nutrients that can help soothe discomfort and support healing. Ultra-Flex Collagen is also a great option for pets with shellfish allergies who can’t tolerate glucosamine. It can be used on its own or alongside joint supplements like ArthroStride to promote joint repair, improve mobility, and reduce wear and tear on aging joints.
"My name is Benji. I am 14 year old Yorkshire Terrier and a few years ago I started have episodes where I couldn't catch my breath. My owners took me to the vet and were told it was a collapsing trachea. My owners do not like pharmaceutical medications so they did web search and found you. They ordered for me theUltra-Flex Collagen For Pets. After about a month my symptoms were gone. I have only had a couple of episodes and that has been on very cold days. Thank you for providing this wonderful product because I was very scared when not being able to catch my breath."
Ultra-Flex Collagen has been one of Ask Ariel’s most effective natural supplements for dogs with collapsed trachea. Eggshell membrane for collapsed trachea helps strengthen and support the rings of cartilage that keep your dog's airway open. Ultra-Flex contains clinically tested NEM® eggshell membrane, a whole-food source of collagen that promotes easier breathing and helps reduce coughing and "honking" over time.
Ultra-Flex Collagen is also helpful for dogs with laryngeal paralysis and GOLPP. With these conditions, the laryngeal cartilage no longer functions normally and breathing becomes restricted. Supporting and strengthening the connective tissue may help delay the need for surgery and reduce symptoms.
"This is Buster, adopted from my local shelter 6 years ago. He has a collapsing trachea, so I've been giving him Ultra-Flex Collagen, Soothing Digestive Relief, Gastro-ULC and Power Probiotic for about the last 6 months. He has had great relief from his symptoms and the vet said his breathing sounds better than it did 6 months ago! His intermittent diarrhea is no longer a problem either...I’m very pleased with how well these products are supporting Buster’s health. Buster also uses Lypozyme for his digestion and collapsing trachea; he is doing so much better since we started with these products!"
We all want our pets to have a soft, shiny coat and healthy skin. Dry skin, brittle fur, or cracked nails can sometimes be a sign of an underlying health condition such as thyroid, kidney, or liver disease. Collagen can help keep your pet’s skin flexible and hydrated — it’s what gives the coat its natural sheen and strength. As pets age, collagen levels decline, and their skin can lose elasticity. If your cat or dog suffers from itchy, dry skin or cracked nails, adding collagen along with Amazing Omegas can really help.
Ultra-Flex Collagen for cats and dogs comes in capsules, which help protect the active ingredients and maintain freshness. The powder is unflavored and works well for most pets when mixed into food.

"Our lil boy, Jaspurr, is doing amazing with his supplements from you (Ultra-Flex Collagen,Power Probiotic,Soothing Digestive Relief) and his diet changes for his IBD. At 17 yrs and 9 months old, he still runs around and plays with his two brothers, Bailey (7.5 yrs old) and Tinker (2.7 yrs old). I switched them all to grain free/gluten free foods and Power Probiotic and they are just great."
"Here is a picture of our two Italian Greyhounds Chip (on the left) and Princess who are nearly 12 years old. Chip has collapsed trachea but we have been giving himUltra-Flex CollagenSupport consistently for over a year which has helped calm the horrible, honking cough he had previously. He still has days when he coughs but it is no longer the coughing that sounds like a goose."
