Yes, we have the dosage to use for Ketamine. And I would start very low to see how it affects my dog. Ketamine is primarily used in cats as a pre-anesthetic, so it's a bit trial and error (okay, NO error here on dogs. My vet has not found the pill form among his suppliers, so I thought I'd check and see if anyone has gotten it from a pharmacy. It normally comes in liquid form for vets but in pill form for people. Yes, it is an interesting drug! I heard of it being effective for severe depression - but didn't know that it creates changes in the liver. Thanks much for your informative note!
