Review on 🐶 Hartz UltraGuard Flea & Tick Collar: 7-Month Protection for Dogs & Puppies, White, Up to 20 Inch Neck by Justin Albright

I bought this flea collar for our one and a half year old Goldendoodle, who came back from Grandma's farm with a few fleas. After about 2 weeks of wearing, we noticed that she had an abnormal appetite. As she ate, she vomited. It's just not normal for a crazy girl. So we took her to the vet. After many tests that didn't reveal anything abnormal, our vet asked us if anything had changed. The only thing we could think of was the collar. She ran a more extensive blood test and just two weeks after the little girl wore the collar, one of the main components began to build up in her system. That's not normal! Do yourself a favor and take it off your pet's shoulders if you've bought one, and if you're thinking of buying one, don't!
