Can anybody help? My baby has what the vet says is a severe flea allergy. She is a 1 year old blue nose and the sweetest thing around. I took her to a friends house this morning and I guess there were some fleas in the yard...now she is covered in welts and even her face is swollen. I gave her a flea bath and only discovered 2-3 fleas and the vet told me to give her some Benadryl (75 mg.) which I did. This is such a severe reaction that I feel horrible for her. She loves going places with me but after today, I am afraid to take her anywhere is case she gets in contact with a flea. No dog parks, no friends houses, no nothing. Any suggestions?
