Our Blue boy had some reactions and our administrated a cortozone booster to assist. Blue Bassets are cursed with usual skin problems, but not a need to worry. You do have a rare breed like us and they do live very healthy, but sometimes costly on the pocketbook lives. Bart has more courage than his half-brother Harley. Harley is a 7 month old 50 lb. Tri and Bart is a 5 month old 30 lb Blue. Write back if you need any info.
