Hello, and thanks for your question. It's good to monitor the weight as the puppy grows simply for monitoring purposes, but the 5-in-1 distemper vaccination does not depend on the puppy's weight. We give the same vaccine dose to a tiny puppy as we do to a large one - the dose is universal, as it's the amount needed to generate the immune response we need. So, now that Chopper is 2 months, she should be vaccinated! Hope this helps!
