What is dosage of cetirizine for dogs?

Answer 1

After asking several vets, no one could say for sure if it was safe and told me NOT to give my dog Zyrtec, and went with benadryl--always benadryl. So l did and it worked, for a while, but eventually my dog built up a tolerance after a while. l did thorough online research and found a specific study on cetirizine (active ingredient in Zyrtec) for dogs, and found that it is safe--only one dog had nausea out of several dozen in the study. DOSAGE WAS 1 MG/ 2 LBS (OR 1 KG) BODY WEIGHT, or one 10 mg tablet/ 20 lbs of body weight...but l suggest erring on the side of caution and giving only half that amount for starters--it might work just fine, your dog won't build up a tolerance as fast, and you're less likely to have to deal with unpleasant side effects if your dog for some reason doesn't react well to it. There were also many other comments out there about other people who have given Zyrtec to dogs with no ill effects. Amazingly, a Google search of ''Zyrtec for dogs'' or just about any other medication will bring up dozens of pages specifically answering your questions. l highly recommend doing a Google search when you're wondering about the safety of ANY human medications for dogs, as many vets aren't willing to recommend anything unless they personally know something for sure is safe through their own experience, whereas the info on Google search comes from people who have researched and talked to vets around the world, as well as answers from some actual vets, and sometimes the pharmaceutical companies, themselves. This gives you exponential personal experience answers over what all of your local vets combined have experienced.
