Sorry for your loss. I know the feeling, My dad (svopro) had to put our dog down because our ass of a neighbor put ant killer along the fence line and never told us. Ava (her name) ate the grass and got sick as all hell. My dad took her to the vet and he said that the posion shut half of her body down including her heart. So we had to put her down. Sorry for your loss man your dog is in my prayers.
