My dog is 25 lbs. Should I give Heartgard Blue or Green for her?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Female | unspayed | 1 year and 2 months old | 25 lbs

My dog weighs 24.5lb on the scale at the vet, but she weighs 25.3lb on the scale at home. Should I give her Heartguard Blue, which is up to 25lb or green which is 26 to 50lb?

She can get the 26-50 lb dose. Heartgard has a wide margin of safety so the larger dose is recommended. It it a better option than potentially underdosing Pudding. You should discuss further concerns with your veterinarian.
