However, do not cause vomiting if your dog is in severe distress, unconscious, has trouble breathing, is in shock, or is not sure of what it ate. There is no need to induce vomiting if your dog has already done it.

  • Intravenous fluid therapy – The vet uses this treatment to flush out any toxins that entered the dog’s bloodstream. At the same time, this treatment stimulates the dog’s kidney to keep producing urine. The kidney will need those fluids since it no longer functions properly due to Oliguria affecting it.
  • Giving medications – to reduce your dog’s vomiting and maintain the kidneys function, your vet will have to administer certain medicines to stabilize your pet. Your vet will also monitor the kidney’s function along with bloodwork rechecks to see if your pet is recovering.
