Rat Terrier FAQ

Is a Rat Terrier a good family dog?

Often, yes, when the daily routine fits the dog. For this breed, the short version is: good in the right structured home. Training, supervision, and enough exercise still matter.

Does a Rat Terrier shed?

Low to moderate. Brush on a routine that matches the coat instead of waiting until the house tells you it is time.

How much exercise does a Rat Terrier need?

Daily walks plus training. Most dogs do best when walks, play, and a little training are part of the same daily rhythm.
