If you do not, the Rat Terrier can become destructive as a way to release pent up energy.
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.
