Dexter looking for rescue sbt x patterdale SAFE

Male terrier cross, approx 4-5 yrs old. Fully vaccinated, chipped and neutered. Dexter is good with people but would do best in a multi-adult household, with experienced owners able to give him the boundaries and training he needs. He is not keen on other males, but could possibly live with a female with the right introductions. He is not good with cats.
