My Dogs entire face is swollen
My dog is a rotweiler, lab, boxer, beagle mix. Today my husband took her for a walk she ate some unknown plants, sniffed some, didn't notice any bugs or bee's but we live in ontario and its cold and the bugs are starting to get confused. About an hour later, my husband noticed her lips were swollen and her right eye. this then progressed to her cheeks and eyes swelling and then it spread into bumps on the top of her snout to the back of her nose. Her entire face, jowels, and eyes are now swollen. She hashad a dose of childrens benadryl which didn't do much and is now having ahalf a dose of adult benadryl. She is still active, eating and drinking, playing etc, she is only 1. any suggestions.
