I was just at the vets today with Peanut. He is 15 wks and 3 1/2 pounds. He was given his first dose of Sentinal at 11 wks 3 pounds. I would wait for the 2 pound weight. It won't take long. Better to be safe. As for Heartguard my vet said Peanut is too young for that so I don't know if it is safe in young puppies. |
