I had to deal with this for many years. All of my dogs were infected. They would take madication for long periods then everything tested OK but months later it would return again. Hope you can get it eradicated. BTW they have never been around any stagnant water. They don't even go into the yard. I blame it on bird droppings but don't really know for sure. They are only let out onto our deck and one doesn't ever go outside except when I carry her |
