Why we chose hydrolysed casein
We built AC for Pets around hydrolysed casein because of the research behind it. It contains alpha-casozepine, a peptide derived from milk protein that has been studied in dogs and cats, including in placebo-controlled trials.
Let customers speak for us
from 72 reviewsOur 2 year old rag doll cross was spraying all over the house despite having him fixed when he was 5 months old. He still occasionally sprays, but it is rare. I think the product has helped him calm down abit
After just one day of using CompaniCalm our dog was much calmer in the car and stopped her anxious barking. We are really impressed with this product and will keep using it. We have also recommended it to friends with anxious dogs.
This product has been most helpful in calming my super active Jack Russell. I have noticed a marked difference in his concentration during training sessions.
Over all very happy with the product.
My Jack Russell is a hyper little man.
He has a lot of personality, one week in using AC and he is much calmer. Now settles in for an afternoon sleep. Training is progressing well.
Settles quicker after hearing loud noises and barks a little less.
Great product 5 stars from me.
Thank you
My dog has anxiety issues,the vet recommended I try Compani Calm.We've been using it for about a month and I have seen a good improvement with his anxiety. I will be continuing to give it to my dog.
Best product to calm my pet, it is so easy to use and my dog loves it.
I have Jilly my 18 month-old Golden Retriever on this and I have seen a good response - she is able to relax in the busy home environment, and settles much quicker when we have visitors. She is now able to sit outside and watch the birds rather than running madly around barking at them, or barking at us to come in. Her training has come along in leaps and bounds as she is more focussed, and she gets more rest at home as she is not constantly on alert. I am a vet and this is a product I am happy to recommend as a supportive agent to training, behavioural management and general dog well-being.
AC was a game changer for my 3 year old anxious chihuahua. After 2 years of antidepressants with little positive effect and lots of bad side effects, I tried her on AC. The change was almost instant. She is now a happy snuggly girl who eats food with AC in it with gusto. She's on 4 times the base dose for her weight and it's working wonders!
Since Fearful Fergie has started on AC she has stopped being fearful!! It’s a relief to come home to a dog that isn’t cowering at the bottom of the yard yawning and shuddering her teeth. The incredibly destructive behaviour has totally stopped- she hasn’t eaten a house window sill since!!!
It’s very comforting to see Fergie calm and relaxed after her tough start in life as a rescue dog. Keep up the good work AC - you have changed this dogs life for the better!

Before your first scoop
How do I give AC for Pets?
Sprinkle the amount shown on your tub over your dog’s or cat’s usual food, or mix it into a little wet food. Use an unpacked, level scoop, with dosing guidelines also published here.
How long does it take to work?
Some owners report a change within 2–4 days of starting. Others notice continuing improvement for weeks. Timing varies by pet. Look for small changes, such as settling more readily or resting for longer.
Is this the same as Zylkene?
Both use hydrolysed milk protein as a source of alpha-casozepine. AC for Pets is a simple hydrolysed casein powder made in New Zealand with no added maltodextrin. Zylkene capsules contain maltodextrin, a highly refined carbohydrate made from starch. In our November 2026 Australian price check, a 450 mg equivalent scoop of AC for Pets cost A$1.85, compared with an average of A$2.93 per Zylkene 450 mg chew, before delivery.
