New puppy kidney issues, any advice?

Hi everyone, I’m reaching out for some advice or similar experiences. I adopted a 12-13 week-old female mutt puppy in late October, she was about 10 pounds at 12 weeks. She’s been having some health issues, and I’ve been tracking everything to figure out what’s going on.

From the start, back in late October, she was eating dirt, which worried me because of risks like blockages or parasites. Her stools were softer in the mornings, which seemed common for a puppy her age but could be from diet changes or stress. At 13 weeks, she’d poop twice in the mornings: once normal, then loose almost-diarrhea right after, possibly from food transitions or worms.

In early November, I started looking into deworming because of possible parasites. I learned that dewormers can cause temporary reduced appetite and sluggishness, usually lasting 1-2 days.

This past week, things got more concerning. On Wednesday, my puppy was lethargic and not eating, with a history of morning loose stools but normal ones otherwise; she did eat a little later (about half a cup).

Today, she had bloodwork showing elevated kidney levels (but not alarming), got one dose of antibiotics, and is staying overnight for more antibiotics and fluids, with repeat bloodwork planned this afternoon.

She’s at the vet now, and I’m hoping for good news on the redo. Has anyone dealt with similar issues in a young puppy—lethargy, GI problems, and kidney stuff? Any tips on recovery or what to watch for? Thanks!
