I used to have a little Shih Tzu that had a severe flea allergy. When they are allergic to fleas it only takes one flea to send them into a horrible state. The flea just walking on their skin starts the reaction. The flea feces also cause a severe reaction. They will itch and scratch though you might not see anything on them. It's awful. If left untreated a form of eczema will develop on the skin. Then usually steroid shots are the only relief. |
