You can purchase a 1% injectable (which can be given orally) solution of ivermectin in your local pet/feed store. Dosing can be 0.05 mg/lb once monthly. A 1% solution contains 10 mg/mL. 150 lb x 0.05 mg/lb = 7.5 mg which would be equivalent to 0.75 mL once monthly. Please note that this dosing is the preventative dose of ivermectin. It doesn't treat adult heartworms which are addressed with melarsomine (Immiticide). It's important to have Winston heartworm tested prior to dosing with ivermectin although ivermectin wouldn't be harmful even if he were currently heartworm positive.Please respond with further questions or concerns if you wish.
