Additives used in the production of vaccines may include. 1  suspending fluid (e.g. sterile water, saline, or fluids containing protein); 2  preservatives and stabilizers to help the vaccine remain unchanged (e.g. albumin, phenols, and glycine); and. 3  adjuvants or enhancers to help the vaccine to be more effective.
The other element is a standard Yorkie that falls under or over the expected weight and/or size range. Breed standards have changed. The AKC used to list a minimum weight of 4 pounds (1.81 kg). Now, there is only a maximum weight of 7 pounds (3.17 kg) for a full grown, adult Yorkie. Even with this change on paper, most Yorkshire Terriers fit into the 3 to 7 lb. (1.36 kg to 3.17 kg) range. A dog smaller than this, fully grown, would be considered too small and may have size related health issues.
In my experience, growth charts are a very rough guide, and have been accurate for me about 50% of the time. The best thing a new Yorkie owner can do to predict the weight of their puppy is to triple the puppyâs weight at 8 weeks, or double the weight at 12 weeks.This is a very good way to guesstimate the weight of your Yorkie as an adult.Taking this prediction into consideration with (at a minimum) the weights of the parents and you will have a very good idea about the eventual size of your puppy.n my experience, growth charts are a very rough guide, and have been accurate for me about 50% of the time.
