Hi everyone. So lately I've noticed some issues with Stanley and I'm wondering if it could be allergies. He's been doing this weird snorting noise and from the research I've done, it sounds like the reverse sneeze. It's awful to witness b/c it seems like his hyperventilating or something. But luckily he stops after a few seconds. It seems to happen at different times though, nothing really consistent to see what triggers it. The other thing I noticed is when we'd take him to puppy class, his eyes seemed a little red and he would sneeze regularly. The classroom had a lot of dog hair and dust bunnies in the corners. The other symptom is the scratching. He seems to scratch a lot lately. We did find a couple of fleas on him last week. I treated him with Advantage and have run a flea comb over him. He appears to be flea free now but still scratches. Does this sound like allergies? Should I take him to the vet? Other than those items, he seems very healthy so I'm not sure what to do....
