We took our adoptee Sadie to the vet this week to get checked over and sure enough she's got heartworms. She's going back tomorrow to receive a pill to kill the larvae and they're keeping her all day to make sure she does OK. Then in Oct. she's getting the big guns treatment. The vet says we'll have to keep her quiet and calm for up to 3 weeks to prevent pieces of the dying worms from breaking off and causing an embolus which could kill her. I already knew all this because my GF had her dog treated last year. My GF's dog is a pretty sedentary indoor dog so it was easy to keep her quiet, but Sadie is an outdoor dog and her boon companion is our wild little boxer puppy, Violet, who loves to run and play with Sadie. So I guess my question is....has anyone here had their dog treated for heartworms, and what was it like? Any and all info is greatly appreciated! TIA!
