? what to give 3lb yorkie to prevent flees and heartworms Hello I'm wondering what you guys give your small yorkie to prevent flees an heartworms? I was giving him frontline and heart guard but now I've found out my vet is not going to carry frontline anymore. I would really like something that is combined into one pill but I've read because he weighs less then 5 lbs then you can not give them anything that is available in the combination pill. Just wondering what all my options are before going back to the vet. He is 1 an 1/2 years old weighs 3 lbs and very healthy. Thank you for your time |
