I used the hartz 2 in 1 flea and tick spray on my dog and ever since I have had nothing but problems. The night I sprayed her with it she started drooling and laying around. She’s usually a really happy dog with eyes that light up when she looks at you. That’s how I know she was sick. She still itched even though the fleas were gone and started to get a rash. I immediately gave her a bath with oatmeal shampoo. She made it throught the night and stopped drooling. She still had the rash that turned into wart looking things that pop and ooze pus. I gave her another bath today and a benadryl. She still has that sad look in her eye. I hate hartz. She looks so miserable and I feel so helpless. She has bald spots, rashes, warts, and is still itchy. DONT USE THIS PRODUCT.
