You might have heard of the 3-3-3 Rule. If you aren’t familiar with this rule, it is a valuable tool to use when you take home your new pup! The 3-3-3 rule is designed to help set expectations for the first 3 days, the first 3 weeks, and the first 3 months of your new pet's transition into your home.
In the first 3 days: 
- Create a Comforting Space. Your dog might feel overwhelmed, scared, and unsure- make sure to give them a space of their own and something comforting like their own bed and plush toy to snuggle up to. This KONG Comfort Kiddos Elephant has a removable, low-tone squeaker which is great for the first few days with a shy pet. Tip: If you have children, talk to them about your new pet in a way that they will relate to their own feelings of nervousness.
- Meet & Greet. If you have another dog, it’s best for them to meet outside of the home, even if they’ve already met at the shelter. One way to do this is to have the dogs walk on opposite sides of a residential street with another family member or friend, in the same direction, getting closer as you go, then eventually making your way to the backyard or area near a door of your home. Watch this video: Dog & Cat Introductions with Dr. Karen B. London, to learn the correct way to introduce dogs with dogs, and dogs and cats, and to learn what to avoid.
- Baby Steps. Make sure to give your dog a tour of your home’s exterior before you head inside so they get the new smells, have a chance to go potty, and get the lay of the land.
- Hide & Seek. Your dog might not be comfortable coming out of their shell and may refrain from eating or drinking at first. This is normal behavior for a dog who has gone through a lot of changes. Speak gently, in a calm tone until they warm up to you and your family. Your dog may hide under tables, chairs, or in their crate. You can invite them out and try to entice them with treats, but never force them out of their secure space until they are ready on their own.
- Testing Boundaries. For parents of human children, you may be familiar with this one already – with ‘threenagers’ or teenagers! Try to have patience with your new fur child as they navigate what is acceptable and what’s not in their new home.
In the first 3 weeks:
- Settling In. Your dog should start settling in and feeling at home.
- Routines. This is a great time to establish daily routines for feeding, walking, playing, and downtime.
- Familiar Environment. Your dog is learning their new environment and you may notice them anticipating your movements a little bit more.
- Personality & Quirks. Your dog’s personality may begin to shine through! This is when you might also start to see previously learned behaviors surface. Just remember, it is never too late to teach your dog new behaviors. Give your dog some time to work out the kinks – this is all still very new to them, and some behaviors may dissipate with more time and effort on your part.
In the first 3 months:
- Set Routines. You and your dog’s routines should be set by now. They should be anticipating your cues for walks, feeding, treats, etc.
- Bonding & Security. You will have started to build a bond by now which gives them a sense of security. They know they are home, and you are their family.
- Comfort & Relaxation. Your dog should feel a sense of comfort and the ability to relax at this point.
