Best supplement I have tried!
I have Mudi. As puppies/young dogs they can eat and eat and eat and still stay thin by running all their food off. I started my newest girl on this two weeks ago and she has put on a noticeable amount of weight & no loose stool like other supplements. This puts weight on better than anything else I’ve tried & I haven’t even used a lot out of the bag. They are in good condition after starting this, not “pot belly” or fat, just getting more fill! From now on I’m going to keep this on hand at all times!

Amazing product that works
We’ve got this in authorship! This product has worked wonders for my allergy prone animals. It has improved their coats tremendously and to top it off they absolutely love it in their food. Will continue to order this product

Our senior pup loves it!!
Our senior pup (13) absolutely loves this stuff!! We got it this week and haven’t had any stomach troubles (thankfully unlike other reviewers), it has definitely gave her a big energy boost as now we have to power walk when we take her out (compared to when it was a very slow leisurely walk before), and hopefully we’ll see some weight gain soon :) 1 month Update Her coat is the shiniest and softest its ever been, she also visibly gained some weight so I say this product works really well!! She still can’t get enough of the flavor, and she still seems to have more energy :)

Effective, but start slower than the directions say!
I’m really pleased with the healthy weight my dog has put on using this. She’s a picky eater and usually turns her nose up at supplements, but she gobbles this up when mixed with a little water. I’m giving it 4 stars because even though I followed the 'start slow' instructions, it still gave her a bit of a loose stool for the first week. If you have a dog with a sensitive stomach, I’d recommend starting with even less than they suggest. Once she adjusted, she was fine and the results have been great.

Waste of money
The dog won't eat this stuff. I have a small dog who needs to gain weight, so I put a little of this on her food with a little warm water mixed in as instructed, and she wouldn't eat it at all. She ate the edges of the food and avoided the section that had most of the product. I don't recommend it.

Dogs need supplements too.
We add this supplement to our dog's food every morning. Just like us they need a good diet to maintain. muscles. I have a two Dutch Shepard protection dogs and along with raw foods, this supplement is a must in their diet.

Picky Eater Said No Thank You
My 2 yo standard poodle is a hard keeper, it’s incredibly difficult to put and keep weight on him. He’s also the world’s pickiest eater, and sadly Healthy Weight did not pass his test. I followed the instructions to a T, starting with 1/5 the recommended dosage for his weight and mixing with water, but he wouldn’t touch his kibble with the supplement on it. He wouldn’t take it on treats, either. I tried mixing it with bone broth and baby food before putting it on his kibble, no luck. I have managed to mix 1/8 a dose in his favorite wet food, but any more and he puts his nose up at it. I was hoping this would work as it’s more nutritious and natural than other caloric additives, and I think Rogue is a great company and this sounds like a great product (at a great price!) but if you have a super picky eater, they may not like it.
