We got Hartz flea and tick stuff. The little stuff that comes in a box. We bought a puppy and she had fleas so we were trying to treat our cat and other dog. Needless to say, it gave them both chemical burns and it cost us sooo much money to treat them. My poor babies were in so much pain and it hurt to see them in that condition. 🙁 the stupid shit didn’t even work so I put my babies in pain for nothing all by purchasing Hartz products. Disgusting. Company needs to burn to the ground.
