Hello everyone. This is my first time posting and I am a first-time dog owner. 2 months ago my fiance and I adopted an adorable, healthy Italian Greyhound at 8 weeks. He is now 4 months old and he is in relatively good health (aside from missing a testicle [only 1 descended]).
Last Wednesday, we woke up and he had a swollen nose, not really the snout, just the nose itself. We took him to the vet immediately that day, but by the time we'd gotten him there most of the swelling was gone (luckily we had pics). She checked his temperature (no fever), looked up his nose (nothing was lodged that she could see), felt around the area (he didn't show any signs of being in pain), and checked his lungs & heartbeat (all normal). She gave him a corticosteroid shot anyway and told us we could give him 11 mg of Benadryl every 12-24 hours as needed.
It is now almost a week later and the swelling has been completely gone for several days, but he has continued to sneeze, sniffle/runny nose and show a little bit of gunk in the corners of his eyes a few times a day. The runny nose is only clear, not green or yellow. The watery eyes is mostly clear or whitish. His energy levels are normal, he'll play like a fiend when he's not asleep, no vomiting or diarrhea. He drinks a lot of water and eats normally but he's been picky with the hard kibble lately cause he's at peak teething time. He'll eat anything soft we give him (including the couch). I would say he's itchy, mostly on the top of his tail and his paws, and he does paw at his ears but only when he's laying down...if that makes sense.
We have the vet again on Thursday morning for his 3rd round of vaccines, and we will obviously consult with her again about the respiratory symptoms, but in the meantime I'm wondering what this could be. Is it a cold? Is it a residual allergic reaction to whatever made his nose swell? I know upper respiratory allergy symptoms are semi-uncommon in dogs (at least that's what Google has told me).
Any help is appreciated!
