What to feed new pup?

Introducing my first Basset ever, Murphy 🙂 she’s going on 3 months of age, and she’s been dewormed and received first round of shots as well as begun on Simperica trio.

She’s been doing very well and growing very fast! But we have two issues that I need some advice on. I did already ask the vet, but he told me to wait it out unless it changes drastically.

But her poos have went from solid on day 1-2 (she only ate Walmart brand food) to very soft, sometimes wet soft, not diarrhea since I switched her to Stella and Chewy puppy food. (It was on deep discount and I wanted to try it out for her).

But my question is, are Bassets prone to digestive issues? She has no loss of energy, no blood, no vomiting, no other worrisome signs, just these icky soft poos. She’s been with me almost a month now, so she’s had the same food the entire time.

And the second thing, she eats the poos sometimes. I have never had a dog do this and I’m so confused on what to do about that. Her next visit is coming up next month, so for now I just clean the poos off the pads the moment she takes them so she can’t eat them.

Does anyone have any advice on brands to try switching to next? Or ingredients I should be avoiding? Thank you. 🙂
