My puppy ate a toxic lily. Should I worry about kidney failure?

Hello and thank you for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Nimi getting into the belladonna lily.

Sounds like the worst is over for her as far as this exposure situation. I would continue to monitor her for any other signs of ongoing problems from the exposure like vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia, tremors. If any of these signs return or linger, I would advise seeing your veterinarian ASAP.

Kidney failure associated with toxin exposure is most often seen with an initial increase in thirst and urination frequency but as the kidneys become more damaged, they begin to shut down leading to a decreasing amount of urine produced. The kidneys can go into complete failure where no urine is produced at all and the pet quits urinating.

So if you are noticing an increase in thirst and urination frequency/large volumes of urine produced or you notice no urination at all, I would consult your vet ASAP so they can get blood and urine to make sure the kidneys are functioning normally. Even if you don't see those signs and you want to make sure everything is ok, go to your vet and let them run some tests.

In my opinion, sounds like the worst is over and preventing further exposure to the lily is all you need to do. Again, if you are concerned, your vet can run some tests on her urine and blood and evaluate her organ function.

Good luck and I wish you and her the best!
