About This Item

Details

  • Dyne is a powerful nutritional supplement that provides additional calories to support pups 8 weeks in age and older—active, pregnant, lactating, underweight, and senior.
  • This high-calorie, low-volume formula supports performance and endurance for working and active furbabies, and it provides pregnant or lactating pups with important nutrients.
  • The concentrated calories in Dyne don’t limit stomach capacity for your furry friend’s normal diet, providing a dense form of energy.
  • Shake well prior to feeding. Can be fed directly or poured over food. With high fat and a sweet vanilla flavor, Dyne is highly palatable.
  • Consult your veterinarian for advice. Do not feed cats or kittens. Not for human consumption.

Should I feed my adult puppy which is 7 pounds a 1/4 tbsp twice daily or two serving 1/2 tbsp daily

Answer by monshiaNov 05, 2023
1/4 Tbsp Twice Daily

How long is a bottle good for? The bottle I have previously purchased does not have an expiration date.

Answer by ChewyMay 06, 2018
The expiration is normally pushed out a year. We'd recommend storing in a cool, dry place for best results.

I need high calorie but low sodium for a dog with heart issues. How high is the sodium in this suppliment?

Answer by ChewyMar 20, 2019
There is 0.00176 grams of sodium per 30 milliliters of Dyne.

Where can I find the expiry date on Dyne bottle

Answer by ChewyJun 01, 2020
You will find a lot number on the label that can indicate when the product is good until. The first two numbers of the lot indicate the year it was made, and the second two numbers indicate the month. For example, if a lot number reads 1707 for instance this would indicate the product was made in July of 2017. This product has a 3-year shelf life so the expiration date would be 7/2020.

Helpful for dog not eating enough

I like having these high calorie gels when my pup is going through some sort of recuperation. Whether he's not eating enough or just having a stressful situation

I like having these high calorie gels when my pup is going through some sort of recuperation. Whether he's not eating enough or just having a stressful situation that may be affecting his health. These boost his caloric intake (which often goes down for him when stressed or dealing with health concerns) and help get some vitamins, minerals, and typically electrolytes in him. This one has a vanilla flavor. It smells very sweet. My dog will eat it, but he seems to tire of it pretty quickly. He seems to enjoy the high calorie gels that have malt or other flavors to them. This one seems more affordable than the others, though. If you think your critter friend needs something like this and responds to sweeter flavors, this might be the one for you.

My pitty mix girl has a high metabolism and had lost a significant amount of weight while she was in training/boarding for a month. I used Dyne and was able to get her weight back up within 2-4 weeks. It truly works and she enjoyed the taste!

I have high drive German Shepherds. One in particular, is constant energy and is hard to keep weight on. Adding this was a life saver and helps him maintain his weight. He loves the taste too....absolutely no issues with getting him to eat it.

Underweight foster

Pepper belongs to my niece in California. She found this very undernourished pup on a busy road and needed to add something to her diet as she wasn't eating enough. I ordered the supplement to be sent straight her and she is thrilled so far the pup has gained 2 lbs in 2 weeks and is eating much better. Thank you for sending it to her in such a timely manner. We couldn't be happier with the service we get from Chewy!

My persnickety old lady took to this stuff immediately, and her weight has been returning to a healthy range much to my relief. I just can't figure out why they made it vanilla. Such a weird choice for a dog supplement. And especially off-putting when paired with the product's appearance. I suggest peanut butter or chicken flavor. Even with the weird smell it's going into our rotation. The dog likes it and it works.

We originally bought this to add to his food to help him gain some weight. Now he is a perfect weight, but he just loves this on his food and is not happy for the food alone. He is worth the price!
