Sammy has a URI and is on Clavamox, for 2 days so far. However, he can only breathe thru his mouth - he has complete nasal blockage and gags/dry-heaves every couple of hours, and/or when eating - sometimes getting up clear mucus, sometimes yellow. Fortunately still eating well. Has anyone experienced this and if so, can you recommend a home treatment? The vet wants to look inside (laproscopically) to see what the blockage is (they say full nasal blockage is uncommon??), but that is very expensive. I am so scared for his well-being, he is my youngest (1 yr. old) and my baby, and it is so hard to see him like this; there has to be something more I can do!
