I have been using the supplements from NuVet Labs for a few years now for my golden doodle and am very pleased with how well the supplements from them work. We started our dog with them when she was 10 weeks old, she is now 4 and has been very healthy. The dog takes the supplements every day as part of her routine, and the dog will run over if the bottle of supplements is shaken and views them more as treats than medicine. We will soon be getting the joint supplements from NuVet Labs as well as a preventative measure because she runs and exercises hard and we would like her to stay healthy as she ages. Overall I am very pleased with how well the products from NuVet Labs have been working, I will definitely continue to use them and I cannot give their products a higher recommendation!
