I bought HARTZ 4 in 1 on Thursday 7-12 and applied it late that evening. We noticed that our 10 yr old Yorkie was a bit SLEEPY and LETHARGIC but we didn’t get alarmed until Friday evening when he had TROUBLE WALKING, NOT EATING OR DRINKING and had PUSS forming around his EYE.
Knowing his symptoms were due to POISONING, we immediately BATHED him with DAWN dishwashing liquid and he started to come back around to his old self hour by hour he got better and better.
PLEASE DO NOT USE HARTZ 4-1!!!!! These products contain insecticides in order to kill the fleas but can also kill your pet!
