I traded a puppy one time and the puppy unknowing to me it had Pneumonia. I kept the puppy isolated with a humidifier in a closed room. I gave him clavamox which didn't help. I then went to the nutritional center and got "Naturade Children's EXPEC". It took about three weeks but, he made it. He is now a finished champ. I also put him over my hand and pat on his back every AM & PM. Hope this helps. This expectorant has Guaifenesin in it. Praying for your baby to get well soon.
