My beagle/blue heeler/ blue tick mix puppy accidentally igested about 1ml of my daughters liquid hydroxizine that she spilled on the floor. Now she has bad diarrhea. Has she been poisoned? Do I need to contact my local animal hospital for an emergency visit?

Thanks for using Petco Pet Education Center, formerly Petcoach. The hydroxizine itself doesn't usually cause diarrhea (we use it in dogs too). However, I worry that there could be an inactive ingredient causing Bayley trouble (artificial sweetener? alcohol? flavoring?). If the diarrhea is still profuse or if you see any other signs, call the Pet Poison Helpline and head toward the nearest emergency vet. The Pet Poison experts will also consult with your veterinarian on the recommended treatment throughout the case. Be sure to have your daughter's bottle of medication with you to give them all the ingredients, strength, etc. Pet Poison Helpline 855-764-7661 Best of luck to you and Bayley.
