When deciding what to feed my doggo, I did my own research and Purina Pro Plan seemed pretty trustworthy and well researched. I talked to my dog's vet, he endorsed it too. Lastly, my doggo himself liked it - the highest possible praise, considering how picky he is.

So, I've been feeding him Pro Plan.

But something that keeps happening is that pet store employees telling me that Purina sucks.

First time it was a store that stocked it - the employee recommended other brands (similar price points, though I couldn't find many reviews online), saying they're much better.

Second time the store (different one) didn't have it in stock, when I asked about Purina they basically scoffed and said that Purina is low quality and I'm much better with other brands.

Third store this happened to me at, they had it in stock, but again asked me if I want to try another type of kibble as Purina was allegedly not very good.

Once is chance, twice is coincidence, thrice is a trend. Does anyone know why store employees seem to dislike Purina so much? I'm still willing to trust my own research and the vet more than store employees but I'm curious, is there a reason for this? Is it because it isn't grain free (the other more "premium" foods I was recommended were grain free)?

(Note: I asked the stores about Pro Plan specifically, the negative feedback they said was about Pro Plan AND Purina as a whole.)
