I have been using various products from NuVet Labs for 3 years now and am very pleased with how well the products from them have been working for us. This is our sixth cocker spaniel and the supplements we have been giving him for the last 3 years seem to have been working great, there have been no outstanding medical issues with the dog and the dog always has energy to spare. Alex from NuVet Labs has been a spectacular help, she has always helped us find products that will work well with our dog. We also referred NuVet Labs to a neighbor with a dog that was needing a $5000 operation, they started giving her the supplements and the dog isn't 100% healed but no longer needs to go in for the operation. All in all, I am very satisfied with the products from NuVet Labs, I will definitely continue to use their products and I cannot recommend them more!
