My dog ate Loxicom post-op, has dark stool. Should I call vet?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Male | neutered | 6 months and 17 days old | 22 lbs

The last part of my question was cut off. It read 'The dog has been eating and drinking normally, had a looser, darker stool yesterday, and the rest of his stools since then are all normal. He has been happy playful (despite trying to keep him calm post-op!). What should I do?

I would still have Rover checked out by a vet to be safe. Overdoses of Loxicom can cause acute kidney failure, and that will take a couple of days for it to show symptoms. It's best to have his kidney function checked now with bloodworm and again in a few days to make sure they are working well. I'd bring him into a vet now. Best of luck, I hope this helps!

    That's not good that your husband overdosed Rover with the Loxicom! Two signs of toxicity from it are diarrhea and dark stools, which indicate bleeding from the upper GI tract. Unfortunately the rest of your post was cut off, and the last bit of information I got was "and the rest ar...." I'm not sure what other symptoms he may be showing, but because he is showing two signs of toxicity, it's best that he's seen by a vet right away. Too much of it can result in severe gastric ulceration and acute kidney failure. He needs to be treated for the black stools and diarrhea, and have his kidney function checked to make sure they are working ok. Please take him into a vet now.
