My golden just contracted this and we live in north Oshawa in a subdivison, not a rural area at all and she only goes for walks on the sidewalk and park no dog parks. You don't want your pet getting this it's nasty. She seems to be responding well to the antibiotics and the fever is coming down, it started at 40.2 C. plus her liver enzymes were going up. Our vet says we caught this early so fingers crossed that she continues to do well. Needless to say we will be looking into the vaccine. You would be shocked at how fast this thing attacks your dog. Not fun and scary.
