Can Allegra or Zyrtec prevent my dog's seasonal allergy symptoms?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | 6 years and 9 months old | 100 lbs

Every year in August my dog starts his allergies with his itchy skin and eyes,,if it gets too bad my vet will order prednisone orally which does help. But can I ward off some of the symptoms with Allegra or Zyrtec?

Unfortunately, by law it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to recommend using any drug, including OTC drugs, without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for Dakota. I would give your vet a call to discuss if using an anti-histamine in addition to his prednisone is safe for him. Best of luck.
