My yorkie is a bit big although she was the runt. She's 5.5lbs at 4 months. She just got her rabies shot three days ago along with some other core vaccinations. She had no bad reactions at all. It's like it never happened. But I do think your puppy is too small because when I was making the appointment with pet smart they told me even though she was of age it depended on her weight because she was 2.8lbs when they last saw her. I would probably wait till a year old or 3.5lbs which ever comes first |
