Oh, poor Dallas, will keep sending her prayers and healing vibes. Well, you knew it was just a matter of time, now the next step...I hope your neighbors will take care of your vet bills, but they don't sound like the kind of people that will do that. Whatever action you have to take, you know they have forced the issue. if their dog did it once, he could do it again to one of your dogs or someone elses. Very sad. Makes you wonder why some people bother to "have" a dog. I know you want a good outcome for Diesel too, we'll keep paws crossed.
