Larger dose=less pills

My pup is starting to get older and he’s so over all of his new meds. He’s meant to take 4 Benadryl a day, so I was so excited to find these meds at a higher dosage

My pup is starting to get older and he’s so over all of his new meds. He’s meant to take 4 Benadryl a day, so I was so excited to find these meds at a higher dosage than typical Benadryl so we can cut it down to 2 pills a day for this medicine! Thanks Chewy Pharmacy!

Bailey takes 100mg of benadryl twice a day for a history of mast cell tumor. The only OTC availability is 25mg which also contain additional ingredients I do not want. I am able to get 50mg capsules without additives for my boy.

No matter what we tried, she would not take them. She could smell them in food, taste them in treats. It was hopeless.
