I have two silkies that were quarantined because I had just bought them. I was having a problem with wasps in the area they were staying. I killed them with sevin dust but that left a lot of dust in the area. I cleaned up as much as I could. One was perfectly fine but this silkie developed a respiratory like problem. The roof of her mouth is swollen and when she breathes it sounds raspy. It had been white on the roof of her mouth and I think that is the dust that she was inhaling. I removed her from the area and she is in a temporary section now. She eats and drinks and does everything else fine. I think it was the dust in here. I gave her tylan for it. The white on the roof of her mouth is gone now but it is still swollen and her breathing is still raspy. I don't know how long it should take for me to see improvements. Any thoughts?
