My dog has been sneezing excessively this past week and when he sneezes it's very loud. He seems scared and is not as active as before. What is wrong with him?

I am sorry that Leo is sneezing a bunch! He is really cute! It sounds like he may be having some allergies. You can try to give him 1.5 tablets of adult benadryl (25 mg each) to see if that helps. If the sneezing continues, worsens, or if he isn't eating/drinking, I strongly recommend contacting your veterinarian for an exam (to ensure it isn't something more serious like a foreign body stuck in his nose), possible diagnostics (for example blood work, and/or x-rays), and medication. Please feel free to contact us again on the forum or set up a consultation if you have additional questions or want more information.
