What did the vet say about frequency of dosing, hali? We're not vets here and don't know enough about your dog to give you good advice. The dosing might differ depending on weight and general health of your dog.
"We are--each of us--dying; it's how we live in the meantime that makes the difference."
"It's not what you gather, but what you scatter that tells what kind of life you have lived!"
"Be kinder than necessary, for everyone you meet is fighting some kind of battle."
