Questions & Answers

3 Customer Questions

How long does the expiration date last?

Answer by Chewy • Jun 11, 2025
The shelf life of this supplement at the time of manufacture is 3 years. Chewy requires that products be shipped with a minimum of 6 months of remaining shelf life. The remaining shelf life of any product sold by Chewy will depend on what the shelf life was at the time of shipment (at least 6 months) and how long it has been on Chewy’s shelf so it could be anywhere from a few months to just under three years.

How long does it last in good condition if I mix it with dry food?

Answer by Chewy • Jul 01, 2025
Once Dyne Pro has been mixed with food we recommend serving it immediately to maintain its freshness and nutritional value. If the mixture is not consumed right away, it should not be left out at room temperature for more than 2 hours, especially in warm environments. After that time, the risk of bacterial growth increases, which could affect the safety and quality of the food. Please note that the safe duration may also depend on the type of food it’s mixed with. For example, wet or raw foods spoil more quickly than dry kibble. If you’re unsure, it’s always safest to refrigerate any uneaten portion and use it within 24 hours.

Does is have to be refrigerated?

Answer by Chewy • Jun 20, 2025
This supplement does not need to be refrigerated, but should be stored in a cool, dry place.

I have Belgium Malinios mixes. So basically velociraptor on meth. They eat 6 cups of food a day and still burn through it all. My trainer recommended this supplement and it’s been excellent. They love it. They get the additional calories they need and are happy, healthy and spoiled!

I bought the DYNE to help my dog to regain her appetite, I ended up receiving two bottles but it was too late to save her and she passed away. I called Chewy to return the unused bottle and I was told to donate it to a shelter which I did. Some days later I received a package from Chewy that brought me to tears, Guillermo and the Chewy family team sent a Token of Remembrance for the loss of my beloved Bella. It is amazing your concern for the pain that is in my heart and I am forever thankful..

Worked wonders!

I believe this my sick puppy feel better and gave her the energy she needed to get over an upset tummy. She wouldn’t eat plain rice and chicken, so I tried this

I believe this my sick puppy feel better and gave her the energy she needed to get over an upset tummy. She wouldn’t eat plain rice and chicken, so I tried this Dyne Pro HG. She loved the flavor, kept it down and gradually started feeling well enough to eat dog food again.

It’s working!

My 16 yr old little girl had dental surgery and four more teeth removed with pockets of infection. Of course she was put on an antibiotic which killed her already

My 16 yr old little girl had dental surgery and four more teeth removed with pockets of infection. Of course she was put on an antibiotic which killed her already lack of appetite. I was frantic trying to get her to eat and stomach healthy after her dosage was done 10 days later. She quit eating any breakfast but I was able to get slippery elm down her with deli low sodium roasted Turkey. Was going to order Dyne as have used it in the pass but then saw this one with pre and post biotics so thought this might work for her better. Thank heavens she licked it up and after 3 days her appetite is coming back, she’s wagging her tail again and looking so much better and happier. What a relief! Thank you Dyne!
