Can we use this Hi, Star is now 5 months old and weighs 2 1/2 pounds. Vet recommended Advantage multi for her. I read that it is for dogs at least 3 lbs. Has anyone used this product with a small baby before. She weighed 2.1 lbs when I brought her home in March and is now just reaching 2.8 lbs. so I'm thinking it might be a little while before she hits 3 lbs. Thanks |
