I am a new puppy owner and I’m just now getting the hang of what I should do for my puppy as far as fleas go. I purchased Ultraguard Rid Flea and Tick Dog Shampoo with Oatmeal for my 11 week old German Shepherd. It said that it’s safe to use at 8 weeks so I felt comfortable using it. Big mistake. Moments after her bath she was shaking as if she was suffering from epilepsy. It wasn’t a nervous shake, more of a jerky tremor. She also started walking as if she was intoxicated and wouldn’t stop barking at us. I freaked out and thought the worst. The next morning I took her to a vet and I was told that these products have some type of chemical in the pesticides they add to their product that cause neurological damage and even kill some cats. Liberty (my puppy) is fine now, but I’m glad I caught it when I did. She could still be in danger of some kind of permanent neurological damage and I hope not, only time will tell. This product is dangerous and should not be available for purchase.
