Willow keeps getting heartworm over and over this summer and I didn't understand why...until I notice the deer poop everywhere. It was all over in the front yard so I brought her to the backyard instead to do our activities, and it was okay for a while. Then yesterday morning I found some "surprises" in the backyard, but it was too late and she already sniffed it so I think she has worms AGAIN now (her gums are getting paler, but no bloody stool yet). I keep having to give her her heartworm chew twice a month instead of once. I covered that little pile o' poo with a rock, but I still feel that no where is safe. We don't have a fence so they can just come in and out of our property as they please... Is there anything I can do to try and steer the deer (lulz) away from my property? I'll be taking Willow out on a leash from now on (I trust her off leash on my property) to try and avoid the poop... I'm SO frustrated!! My baby is constantly sick.
