Does this have glucosamine to support hip & joints ?

Answer by ChewySep 27, 2022
They do not add glucosamine or chondroitin to the Diamond Performance food. Since It is an all life stage formulation, regulations state you can not add these things to an all life stage formulation.

is this good for helping a dog gain weight and keeping it

Answer by ChewyJun 19, 2019
While this wasn't specifically formulated for weight gain, the feeding amount should be adjusted to your pet's specific needs. If unsure, consult your veterinarian.

I liked the old formula better!

Since completing the switch to the new formula, my dogs have loose stools, internment diarrhea, some vomiting and coat loss. The only diet change has been the ingredients

Since completing the switch to the new formula, my dogs have loose stools, internment diarrhea, some vomiting and coat loss. The only diet change has been the ingredients in the food, grain sorghum. Their stools have been examined, they do not have parasites. The closest food I've found to the old formula is the puppy food. I will try that before I completely switch to a new brand. I've fed Diamond for years and was happy untill this new grain sorghum recipe.

Didn't work for my dogs

My dogs loved the taste I'm sure but it caused them severe gas and one of them was puking. I'm sure it's great food nutritionally but it just didn't go well for

Reliability

Same food we usually get. Love that the auto ship works so well. Like the reminders so that we can adjust the date if we need to.

Good food

Diamond is a good quality brand. Never had any issues. I feed this to a German shepherd/boxer mix who is 11 years old. She has been active her whole life.

Yellow Dog likes it, of course he likes most anything eatable, lol

The fact that I never knew that Diamond had it and that Yellow Dog was supposed to be on it most of his entire life is pretty good. Especially considering the cost

The fact that I never knew that Diamond had it and that Yellow Dog was supposed to be on it most of his entire life is pretty good. Especially considering the cost per month for a 40 lbs + bag in other brands is more than I could ever afford. He was having some weird stool issues and now they are slowly going away, since I have been able to switch him over to the Diamond Performance Formula.

They might be eating less

My herding dogs do seem to be eating a little less which means they feel full longer. As you know aussies and border collies are high energy.

High quality palatable

I like to choose Diamond because it's family-owned and high quality. This food is enjoyed by my active dogs and by my inactive dogs as well I use it as training

Great dog food

I can already tell the different after 2 weeks that it's leaning one a fluffy pup. And I have 2 and they both like the flavor which is a home run as well. Also no

I can already tell the different after 2 weeks that it's leaning one a fluffy pup. And I have 2 and they both like the flavor which is a home run as well. Also no gassy side affects. I'm hoping it will continue to aid in joint comfort for my 10 year old pitbull aswell.
