2 days ago our black n tan JRT had a few spots...followed by a VERY swollen face! In fact she looked more like a Staffy! Our vet who happens to live nxt dr recommended Hay Fever remedy but she returned to normal very quickly so we left it. Now her daughter has done the same thing and has spots on top of her head and randomly scattered over her body. She is itchy so have administered the hay fever tablet......would this be a plant or insect issue...poor little thing has lots of hives now! Any suggestions welcome.
