The normal birth weight for a Wistar rat is between 5-6 grams. Birth weight of less than 5grams can therefore be regarded as low birth weight in Wistar rats.

The Rat Terrier is a small and sturdy dog and should be between 13 to 16 inches in height. The UKC doesn't have a specified weight for standard Rat Terriers as each individual dog has a different weight for their height. The Decker Rat Terrier is slightly larger than the Rat Terrier and should range between 22 to 40 pounds. A male should be 16 to 19 inches in height while a female should be 16 to 17 inches. The miniature Rat Terrier should weigh 10 to 18 pounds and should not be larger than 15 inches in height. The toy Rat Terrier is an even smaller version of the breed.
