It overstimulates their central nervous system and heart, causing canine seizures, heart failure, and potentially death. If your dog struggles with kidney or liver problems, giving them Zyrtec could make the problem worse. This is because Zyrtec can cause urine retention in animals. This isn’t too serious of an issue if your dog is healthy beforehand, but it could exacerbate preexisting issues in your pet.

Their bodies are too weak for a strong medication like Zyrtec, and it could lead to serious issues. The same goes for pregnant dogs. It’s also possible that your dog may be allergic to antihistamines. If you give your dog Zyrtec and see a worsening of symptoms or lack of improvement, then they could be having an allergic reaction to the medication.
