Many allergy medications are safe to give to dogs over the counter. It is always best to double check with your veterinarian regarding the dose and the drug you are about to give. What you have in the picture is generic system and is quite safe for dogs. The dose that I typically use is 0.5mg/kg of body weight every 24 hours. My own dog used to get this. He was 20lb and his dose was 4.5mg every 24 hours. I rounded this to 5mg every 24 hours to make it easier for dosing. So that would be 1/2 tablet every 24 hours. There are other options for allergies as well if antihistamines are not effective but your veterinarian will have to prescribe these. Please let me know if you have any other questions and I would be more than happy to help!

    This is likely very safe to give Buddy but I would call your vet that knows Buddy’s history and to ensure you give the correct dose. Another option is Benadryl if you haven’t tried that. I have attached an article below for more information on Benadryl and dosing information. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl/
