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.
While breed standards do not list height, most Yorkies will grow to be 6-9 inches (15.24 â 22.86 cm); this is measured from the floor to the withers (top of the shoulders). In regard to weight, a Yorkie will grow to be 3 to 7 pounds (1.36 to 3.17 kg).Though this is the breed standard, it is not uncommon for a Yorkshire Terrier to be a bit over this size; he or she may grow to be 8 or even 9 pounds (3.62 or 4.08 kg).n general if you take the weight at 8 weeks and multiple this by a factor of 3, it will come close to the dog's full grown potential. For example: 1 lb. (.45 kg) at 8 weeks x 3 would give you a full grown adult Yorkie of 3 lbs. (1.36 kg). 1.31 lbs.
