We advise all adopters to expect the 3-3-3 rule as a general guideline for introducing a pet to the home: 3 days to decompress (will show nervousness, hiding, reduced appetite), 3 weeks to settle into a routine (beginning to explore and showing personality), and 3 months to build trust and feel fully comfortable in their new home. This period may be longer for shy or extremely scared animals. A shelter favorite, Brussel may come to you a little spoiled. However, he is sweet, eager to learn, and eager to please. Brussel is a major cuddle bug and will grow up to be a giant lap dog. Brussel does great with other dogs and is young enough to grow up with cats.
