17 lb. Lhasa Poo with many allergies. Allergic to bluegrass,fescue,Timothy,Bahia,Ragweed,CockleburSage,Waterhemp,cottonwood,Box elder,Pecan/Hickory,Walnut,Mulberry,helminthosporium,hormodendrum, prnicillin,curvularia,candida albicans,nigrosporia,mixed feathers,house dust &mites,chicken,eggs,soybean,wheat,turkey,sorghum,barley,kelp,tomato pomace,cotton,orris root,jute/sisal,mosquito,mouse epithelium.flea and borderline on many others. I give her allergy shots, from two vials, twice a month. She eats duck and rice food and still itches badly and her belly is black tone instead of pink.
Event though you do the allergy shots it doesn't work 100%. Try antibiotics +/- prednisone during flare ups. Vetcare
