I applied Hartz to my dog Powder yesterday around 2pm. I noticed she was walking a bit weird. I thought she somehow stunned her leg a little bit. She is normally kind of rowdy. I took her out side to let her go potty in the back yard. She was playing around like she normally does but both of her legs were moving in-sync, which was strange. Within about 2 hours she could no longer walk and she started shaking. I lifted her on to our bed to see what was wrong. I gave her a doggy bone to see if she could eat it. She couldn’t muster up the strength to eat the treat. We immediately rushed her down to the vets office with both the Hartz in hand as well as a dog shampoo. The doctor explained what the Hartz product is and told us they will give her treatment as best they can. I will absolutely go ballistic if Powder dies.
