Hey! My vet has a long wait time for appointments but my dog is due for her Trifexis. It's summer in Florida so fleas are in full swing. I found an extra Trifexis pill thats still sealed but it expired in January this year. Is it okay to give to her until I'm able to get her in for a new prescription?
