May have gotten chilled riding in his stroller while you're jogging. A pup that young shouldn't be exposed to the outdoors for any length of time. Best to wait till after Rabies vaccine... 16-20 weeks old. His immune system will be stronger then.
Be very careful, cold-like symptoms can rapidly turn into pneumonia in a young (or old) pup, especially one with compromised immune system (having left Mom early).
Probably healthiest thing to do would be keep him indoors till pollen season passes... |
