We have a German Spitz who has had some breathing problems. Originally when we brought her in, you could hear gurgling. That was last Wednesday. We have had her on about 3/8cc of Tylan 50 once a day since then. Sitting her typing this, it sounds like she still has some sort of gurgling What would our next step be? She is eating and drinking. Right now I am giving her a flock feed 18% crumble, a little oatmeal in the morning once in a while. Both her and the little 10 year old d'Uccle chicken who is keeping her company also got about 8 drops of Poly-Visol in the water bowl over the weekend just to help them out. The little d'Uccle was kinda seperating herself from the others. I do have the Penicillin G Procane 300,000u here.
