I've just bought a new yorkie which is 5 months old now
i'm wondering when can i start heartgard on her and does she need a heartworm checkup before i feed her any heartgard?
and one more thing is,
she is so small, she weight less than 1kg
im wondering if i should feed her the whole dose of heartgard which is for dogs up to 25lbs or i can actually split it?
im worry about the medication would overdose for her cause she is too small..
thanks for any reply
