My dog was dead within hours of being given this supplement. My husband ordered it online and paid $142 for it and proceeded to follow the instructions. On the third day, when the dosage was increased, my dog immediately became lethargic and began vomiting profusely and having horrific diarrhea. He previously acted normally — eating, drinking and active — but he had been losing weight over the past month, so my husband decided to try Nutra Thrive. When our dog died, my husband emailed Nutra Thrive 3 times, telling them what had happened and asking for a refund. He has yet to receive any response.
